Question

Ion has a mass number of 65, 36 neutrons, and a charge of +1

. Identify the element symbol, and determine the number of protons and electrons in this ion.

Answer 1

Copper; Symbol is Cu

Protons = 29

Electrons = 29

Mass number = Protons + Neutrons

•°• Protons = Mass number - Neutrons

= (65-36)

= 29

Electrons is equal to the number of protons in a nucleus.
