And as there must be an equal number of electrons and protons in an element there must also be 47 Electrons in the element. The number of protons in atom of silver is therefore 47. Any atom that contains exactly 47 protons in its nucleus is an atom of silver. Example 2 - Number of Protons in Silver: The element Silver (Symbol Ag) has the Atomic Number of 47.And as there must be an equal number of electrons and protons in an element there must also be 79 Electrons in the element. The number of protons in atom of gold is therefore 79. Any atom that contains exactly 79 protons in its nucleus is an atom of gold. Example 1 - Number of Protons in Gold: The element Gold (Symbol Au) has the Atomic Number of 79.(Note: Atoms must also have equal numbers of Electrons & Protons.) So, if we know the atomic number of an element then we also know how many Protons are in an element and therefore the number of electrons in an element. The atomic number is based on the number of Protons in the atom of an element.
