Question

(i) What are isotopes?
(ii) Which isotopes of C is radioactive?
(iii) Which fundamental properties differ in
1. Isobars
2. Isotopes.

Answer 1

Isobars and isotopes

Explanation:

(i) Isotopes are two or more forms of the same element that contain the same number of protons but different numbers of neutrons in their nuclei. So, they have different atomic mass.

(ii) Carbon-14 (14C) is the radioactive isotope of carbon which contains 6 protons and 8 neutrons.

(ii) Difference between isobars and isotopes:

1. Isobars are atoms of different elements having the same atomic mass.
2. Isotopes are atoms of the same element having different atomic mass.

Answer 2

hlo mate ✌️

(i) Isotopes :

An isotope of a chemical element is an atom that has a different number of neutrons ( as that of the standard atom).

(ii) Carbon-14 ,a isotope of carbon is radioactive in nature and it contains 8 neutrons and 6 electrons.

(iii)

Isotopes :

Isotopes are the atoms of same elements having different atomic mass. [ same atomic no. ]

Isobars :

Isobars are the atoms of same elements having same atomic mass.

Hope it helps ❣️
