Give the number of protons and neutrons in the nucleus of the following atoms when an element has 238 mass number and 92 atomic number give the number of protons and neutrons in the nucleus

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

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

can you attach a picture of the lettuce? : )
