Question

The element has a different number of electrons than protons.

the number of neutrons

the number of electron

the number of protons

Answer 1

All of the options mentioned contribute to making one element different from another. However, the main factor that distinguishes one element from another is the number of protons it has in its nucleus. This number is known as the atomic number of the element and is unique to each element. The atomic number determines the chemical properties of the element. The number of electrons and neutrons can vary within the same element, creating different isotopes, but they do not change the identity of the element.
