Question

The number (p+n) in the atomic nucleus is.

Atomic number
Atomic mass number
Avogadro's number
Mole​

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:

Sum of number of protons and electrons (p + n) = Atomic mass number

Atomic number = No. of electrons = No. of protons in the atom

Avogadro's number = 6.022 X $10^{23}$ = Constant
