Answer 2

Answer:

Atomic number.

Explanation:

Atomic number.

Is the correct  answer of this question .

The number of protons in the nucleus of an atom of an element is known as the atomic number.

The quantity of protons in an atom's nucleus is known as the atomic number. The number of protons determines an element's identity (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).

The number of protons in an element determines its atomic number, whereas the number of protons + neutrons determines its mass number.

Atomic mass is fractional because it is the average relative mass of its atoms relative to the mass of an atom of C-12 isotope taken as 12. Mass number is a whole number because it is the sum of the number of protons and the number of neutrons.
