Answer: The atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons is 6.

Explanation:

Atomic number is defined as the number of protons or number of electrons that are present in an atom.

For a neutral atom:

Atomic number = Number of electrons = Number of protons

Given : Number of electrons = Number of protons = 6

Thus atomic number = 6

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons

Given: Number of neutrons = 6

Thus mass number = Number of protons + Number of neutrons = 6 + 6 = 12.

The atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons is 6.
