Diagram, Steps To Draw The Neon Bohr Model

The noble gas neon is represented by the symbol Ne. It is a colourless, odourless monatomic gas with the atomic number of ten. Inside the vacuum discharge tubes, neon emits a reddish-orange glow. Sir William Ramsay was the first to isolate it from a cold sample of air.

It is, however, extremely rare on the surface of the earth. It’s employed in the creation of glow-in-the-dark ads and signboards. It’s also utilised in the manufacture of lightning arresters, lasers, diving equipment, and high-voltage indicators, among other things. Cryogenic preservation also uses liquid neon.

So, how thrilled are you to hear about Neon’s Bohr model today???

Neon Model by Bohr

In 1911, Rutherford proposed his atomic model. This model accurately described the atomic structure, including the position and number of atomic species.

However, this model was unable to answer certain basic rules of classical mechanics and electromagnetic theory.

Niel Bohr reintroduced the Rutherford model in 1913, but with some significant improvements. The Bohr-Rutherford model was named after this.

This concept attempted to address the Rutherford model’s shortcomings by explaining the stability of electrons in their orbits.

The structure of the atom, the arrangement of distinct atomic species inside the atom, and the charge on individual atomic particles are all explained by the Bohr-Rutherford model.

It also explained why electrons stay in their shells rather than plunging into the nucleus. To aid comprehension, the full arrangement is depicted in visual form.

We must first learn a few words relating to atomic structure before we can begin to discuss the Bohr model of Neon.

• Nucleus: The nucleus is made up of two types of particles, neutrons and protons, and is found at the centre of an atom. The nucleus is a positively charged entity in and of itself.

• Protons: The positively charged species found in the nucleus are protons. The symbol p+ is used to symbolise these.

• Neutrons: Inside the nucleus, these are charge-neutral particles. The sign n° is used to symbolise them.

• Electrons: Electrons are negatively charged atomic particles that orbit the nucleus. While rotating around the nucleus, electrons follow a specific route. The sign e– is used to represent them.

• Shells: Inside an atom, the electrons follow a precise circular path around the nucleus. Orbits or energy levels are other names for this. Every electron has a distinct energy level, and each energy level has a distinct number of electrons.

These shells are designated by the Bohr model as K, L, M, N, etc., or 1, 2, 3, 4, etc. The shell closest to the nucleus has the lowest value, while the shell farthest from the nucleus has the highest value.

This is also the measurement of the energy of electrons in the smallest shell, which are said to be in the ground state.

The electrons in the shell farthest from the nucleus, known as valence electrons, have the highest energy, thus the shell is known as the valence shell. This shell’s electrons are involved in the creation of bonds with other atoms.

According to the Bohr model, electrons can fall from higher to lower energy levels as they release energy or leap from lower to higher energy levels as they acquire energy.

The Bohr model of Neon has eight protons and eight neutrons inside the nucleus, as well as eight electrons circling around the nucleus in two shells, the K and L shells.

Drawing a Neon Bohr Model

Neon is a noble gas that belongs to the periodic table’s 18th group:

The following is the information that we may glean from the aforementioned Neon box:

• Neon has an atomic number of ten.

• Neon has the electrical configuration [He] 2s22p6.

• Neon’s chemical symbol is Ne.

• Neon has an atomic mass of 20.1797.

We’ll now draw the Bohr atomic model for the Neon atom using the information given.

We must first compute the distinct atomic species present in the Neon atom in order to draw the Bohr model.

Let’s start by figuring out how many protons there are.

The atomic number of any atom is always equal to the number of protons in that atom.

The atomic number of Neon is 10, as previously stated.

As a result, the number of protons = atomic number = 10 for the Neon atom.

Now we’ll figure out how many neutrons the Neon atom has.

The following is the formula for estimating the number of neutrons in an atom:

Atomic mass (rounded up to the closest full number) – number of protons = number of neutrons

We can tell that the atomic mass of Neon is 20.1797 by looking at the Neon box above. We get 20 after rounding it up to the nearest whole number.

In addition, the number of protons in the Neon atom is ten, as calculated above.

Fill in the following values in the formula:

The number of neutrons is equal to 20 – 10 = 10.

As a result, the neutron count in the Neon atom is 10.

The nucleus of an atom is made up of protons and neutrons, as we’ve already covered.

As a result, we can now sketch the nucleus of the Neon atom using the numbers calculated above. It goes like this:

Protons are represented by p+ and neutrons are represented by n° in this illustration.

We’ll also figure out how many electrons are there in the Neon atom:

The number of electrons in any atom is always equal to that atom’s atomic number.

As a result, when it comes to Neon atoms,

Number of electrons = Neon’s atomic number = 10

Moving forward, these electrons will be added to the shells surrounding the nucleus of the Neon atom.

We’ll do this by calculating the number of shells in the Neon atom, as well as the amount of electrons that can be added to each shell.

2n2, where n is the number of shells, gives the maximum number of electrons that may be held in a given shell.

Using the above-mentioned method, we can now compute the number of electrons in each shell of the Neon atom.

The maximum number of electrons in the K shell of the Neon atom is 2 (1)2 = 2.

The Neon atom looks like this once these two electrons are added to the first shell:

After that, we have eight more electrons to deal with.

To accommodate these, we’ll compute the number of electrons that can fit into the Neon atom’s L shell.

The maximum number of electrons in the L shell of the Neon atom is 2 (2)2 = 8.

As a result, the L shell of the Neon atom can accommodate all eight electrons.

It’s worth noting that starting with the L shell, electrons in any shell are accommodated in a group of four that’s organised clockwise at a 90° angle.

The angle between electrons decreases as the number of electrons in a shell grows. The electrons will always be added in a group of four.

As a result, the first four electrons in the L shell of the Neon atom will be added clockwise at an angle of 90°. The atom of neon now looks like this:

The remaining 4 electrons are now completely accommodated in the L shell of the Neon atom. Following that, the final Bohr model of the Neon atom appears:

As a result, the final Bohr model of the Neon atom has ten protons and ten neutrons inside the nucleus, as well as ten electrons circulating around it.

In the K shell, there are 2 electrons and in the L shell, there are 8 electrons.

Using the Bohr Model to Deduce Lewis Structure

The Lewis structure of an element is a graphical representation of the valence electrons that orbit the atom.

The dots here represent electrons, while the atom is represented by its atomic symbol. The electron dot structure is another name for this structure.

As previously stated, the valence shell of the neon atom, referred known as the L shell, contains eight electrons. As a result, Neon’s Lewis structure is depicted as follows:

Neon’s Characteristics

The following are some of the most important qualities of neon:

• At normal temperature, neon is a colourless, odourless gas.

• Neon has a boiling point of 27.07 K and a melting point of 24.56 K.

• Neon has a density of 0.00089 g/cm3.

• Neon has a face-centered cubic crystal structure with its atoms grouped in a face-centered cubic crystal structure.


The nucleus of the neon atom, according to the Bohr model, contains 10 protons and 10 neutrons, with 10 electrons circling the nucleus.

The number of protons in an atom, as well as the number of electrons in that atom, is always equal to that atom’s atomic number.

The formula for calculating the number of neutrons is:

Atomic mass (rounded up to the closest full number) – number of protons = number of neutrons

The formula 2n2 gives the maximum number of electrons that may be held in a shell, where n is the number of shells.

The neon atom is made up of three shells, each of which has two or eight electrons.

Good luck with your studies!!
