Question

Give the number of protons and neutrons in the nucleus of the following atoms

Answer 1

The number of protons and neutrons in the nucleus​ : 92 and 146

Further explanation

Given

Mass number = 238

Atomic number = 92

Required

Protons and neutrons

Solution

Mass number=number of protons + neutrons

Atomic number=number of protons=number of electrons

Atomic number = 92⇒number of protons=92

Number of neutrons = mass number - atomic number

Number of neutrons = 238 - 92 = 146
