Aneutral atom has two, eight, eight electrons in its first, second, and third energy levels. this information does not tell us about the atomic number of the element does not tell us about the chemical properties of the element does not tell us about the atomic mass of the element does not tell us about the size of the element

Option (c) is the correct answer.

Explanation:

Atomic mass is the summation of no. of protons and average number of neutrons present in an element.

On the other hand, atomic number is the sum of total number of protons only which are present in an element.

Each element of a periodic table has a different fixed number of protons. Knowing the number of protons or atomic number we do not get to know about the number of neutrons.

For example, atomic number of Na is 11 but it does not tell that Na also contains 12 neutrons.

Thus, we can conclude that when a neutral atom has two, eight, eight electrons in its first, second, and third energy levels. This information does not tell us about the atomic mass of the element.
