Problem 38P

A helium nucleus has two protons and two neutrons. How many electrons would it take to equal the mass of a helium nucleus?

Step-by-Step Solution:

Solution 38P

Step 1:

Given : Helium nucleus has two protons and two neutrons.

Number of electrons would it take to equal the mass of a helium nucleus = ?

Mass of a proton = 1.0073 amu.

Mass of a neutron = 1.00867amu.

Since the nucleus of a helium made up of 2 neutrons and 2 protons, the mass of the nucleus is :

= 2(1.0073 amu) + 2(1.0086amu)

= 4.031 amu.
