Question

Elements are identified by how many protons are in the nucleus of their atoms. The number of protons can be found on the Periodic Table and is called:

  1. Atomic Number
  2. Nuclear Number
  3. Proton Neutron
  4. Atomic Mass

hintHint:

Atomic number is defined as the number of protons in an element.

The correct answer is: Atomic Number


    • In a neutral atom number of electrons and number of protons are equal.
    • Atomic number is defined as the number of protons in an element.
    • Elements are identified by how many protons are in the nucleus of their atoms. The number of protons can be found on the Periodic Table and is called Atomic Number.
