Question

Two atoms A and B have the following composition: Atom A Atom B 17 protons 17 protons 18 neutrons 20 neutrons What are their mass numbers? What is the relation between the species?

Answer 1

Answer:

35,37 = Mass Numbers

isotopes

Explanation:

Mass number = No. of protons + No. of Neutrons

Mass of Atom A = 17 + 18 =35

Mass of Atom B = 17 + 20 =37

Therefore, Masses of the atom A and B are respectively 35,37

If 2 elements have same no. of protons and different number of neutrons it is known as an isotope
