Question

Os 12 which pair of atomic mass number (A) and atomic number
is of isotones?
(A W A= 30,2 = 15
A3L. 2 : 14
(20) A: 3L, Z =15
(ö) A = 30, Z = 14
(c) (i) A= 32, Z=15
(i A= 36.2 = 14
(D) (i) A=1 , Z = 16.
(1) A= 32, z = 14​

Answer 1

Isotone, any of two or more species of atoms or nuclei that have the same number of neutrons. Thus, chlorine-37 and potassium-39 are isotones, because the nucleus of this species of chlorine consists of 17 protons and 20 neutrons, whereas the nucleus of this species of potassium contains 19 protons and 20 neutrons.
