Question

how atomic number for an element is decided​

Answer 1

Answer:

atomic numbers are decided by the number of protons in that element.

Answer 2

Answer:

• The number of protons determines an element's atomic number (Z) and distinguishes one element from another.

• For example, carbon's atomic number (Z) is 6 because it has 6 protons. The number of neutrons can vary to produce isotopes, which are atoms of the same element that have different numbers of neutrons.
