Give reasons
(a) Physical properties of isotopes are different
(b) Argon does not react.
(c) Actual atomic mass is greater than mass number.
(d) 3517Cl and 3717Cl do not differ in their chemical reactions.

(d) 3517Cl and 3717Cl do not differ in their chemical reactions.
(a)
Physical properties depend on atomic mass, and isotopes have different mass number, i.e. they have different number of neutrons. So, isotopes have different physical properties.
(b)
Argon does not react as it has the outermost orbit complete, i.e. 8 electrons in the outermost shell.
(c)
Actual atomic mass is greater than the mass number because the mass number is a whole number approximation of atomic mass unit. In fact, neutrons are slightly heavier than protons, and an atom has over 200 sub-atomic particles.
(d)
They are isotopes of chlorine element which differ in the number of neutrons, whereas chemical properties are determined by electrons from the valence shell (outermost shell), the electronic configuration of an atom. Isotopes of an element are chemically alike.
