Question

Write the difference between Isotopes and Isobars.

Answer 1

Hint: Inside the nucleus, the Nucleon is the pair of proton-neutrons and electrons revolve around the nucleus. All elements show unique properties due to these nucleons and electrons, but there are some elements which are somewhat similar in nature.

Complete step by step solution:

Isotopes	Isobars
Isotopes are atoms with the same number of protons but differing numbers of neutrons.	Isobars are atoms of different chemical elements having equal values for atomic mass.
Isotopes have the same atomic number.	Isobars have different atomic numbers.
Isotopes have a different atomic mass.	Isobars have the same atomic mass.
Isotopes have different numbers of neutrons.	Isobars have different numbers of neutrons.
Isotopes of an element have the same chemical properties due to the fact that their similar arrangement and number of electrons.	Isobars differ in their chemical properties due to the fact that their arrangement of electrons is different.
Isotopes occur at same place inperiodic table.	Isobars occur at different place inperiodic table.
Isotopes have different physical properties from each other.	Isobars mostly have similar physical properties.
Examples:- HydrogenHydrogen-1 (proton (1) neutron (1) electron (0))Hydrogen-2 (proton (1) neutron (1) electron (1))Hydrogen-3 (proton (1) neutron (1) electron (2))- ChlorineChlorine-35 (proton (17) neutron (17) electron (18))Chlorine-37 (proton (17) neutron (17) electron (20))	Examples:- Argon and CalciumArgon (proton (18) neutron (22) electron (18) mass number (40))- Calcium (proton (20) neutron (20) electron (20) mass number (40))

Note: There is another type called Isotones. Isotones are any of two or more species of atoms or nuclei that have the same number of neutrons.
For example: Chlorine-37 protons (17) neutrons (20) and Potassium-39 protons (19) neutrons (20).
