An atom of an element has 29 electrons. ...

An atom of an element has 29 electrons. The nucleus of the atom contains 35 neutrons. Find the number of protons in the nucleus and the mass number.

Text Solution

Verified by Experts

Number of protons = Number of electrons = 29
Mass number A = number of nucleons
= Number of protons + number of neutrons
= 29 + 35 = 64
