- Neutral neon atom

- Atomic number (Z) = 10

- Mass number (A) = 22

Calculations:

1. Protons:

The atomic number (Z) of an element represents the number of protons in its nucleus. Since the atom is neutral, the number of protons is equal to the number of electrons. Therefore, the number of protons in a neutral neon atom is 10.

2. Neutrons:

The mass number (A) of an element represents the total number of protons and neutrons in its nucleus. To determine the number of neutrons, we subtract the atomic number (protons) from the mass number:

$$Number \ of \ Neutrons = A - Z$$

$$Number \ of \ Neutrons = 22 - 10$$

$$Number \ of \ Neutrons = 12$$

3. Electrons:

As mentioned earlier, the atom is neutral, which means the number of electrons is equal to the number of protons. Therefore, the number of electrons in a neutral neon atom is also 10.

Conclusion:

A neutral neon atom with an atomic number of 10 and a mass number of 22 has 10 protons, 12 neutrons, and 10 electrons.
