Question

Mass number A is represented as A= P=N or A= P+N

Pls reply fast, it is urgent ​

Answer 1

Answer:

The number of neutrons is represented by the neutron number (N). Because the mass of these nuclear particles is each approximately equal to one unified atomic mass unit (u), the sum of the protons plus neutrons is designated as the mass number

Answer 2

Answer :-

The mass no. = A = no. of protons (p) + no. of neutrons(n) = n + p

Explanation :-

The number of neutrons is represented by the neutron number (N). Because the mass of these nuclear particles is each approximately equal to one unified atomic mass unit (u), the sum of the protons plus neutrons is designated as the mass number (A).
