Detailed Solution

Neon is a neutral atom, and its atomic number is 10. The atomic number of an element represents the number of protons in the nucleus.

Since the atomic number of neon is 10, it has 10 protons. This remains the same for all isotopes of neon.

In a neutral atom, the number of electrons = number of protons. Therefore, neon has 10 electrons.

To find the number of neutrons, we use the formula:

Mass number = Number of protons+ Number of neutrons

For neon with mass number 20:

Neutrons = 20 − 10 = 10

Hence, a neutral neon atom contains 10 protons, 10 electrons, and 10 neutrons.
