The sum of the mass number and the atomic number for an atom (A-Z) corresponds to the total number of subatomic particles present in the atom. The mass number reports the mass of the atom’s nucleus in atomic mass units (amu). Isotopes are atoms with the same atomic number but different neutron numbers and thus different mass numbers.Given real numbers x,y, the complex number z = x +iy is the point (x,y) ∈R2. Its real and imaginary parts are the co-ordinates Rez = x, Imz = y The complex numbers C comprise the real vector space R2 with the extra operation of complex multiplication: If z = x +iy and w = u +iv, define (Vector) Addition: z +w := (x +u)+i(y +v)

Suppose, z = x+iy is a complex number. Then, mod of z, will be: |z| = √(x 2 +y 2) This expression is obtained when we apply the Pythagorean theorem in a complex plane. Hence, mod of complex number, z is extended from 0 to z and mod of real numbers x and y is extended from 0 to x and 0 to y respectively.
