Question

What is the relation between the
no of protons(p) , no of
neutrons(n) & mass number(A).

Answer 1

Explanation:

The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in any atom is its mass number minus its atomic number

Answer 2

Answer:

As we know that

• Mass number (A) = no. of protons(p) + no. of neutrons
• A = p + n

n = A - p
