Answer 1

Answer:

Explanation:

Isobars:

Isobars are atoms (nuclides) of different chemical elements that have the same number of nucleons. Correspondingly, isobars differ in atomic number (or number of protons) but have the same mass number. An example of a series of isobars would be 40S, 40Cl, 40Ar, 40K, and 40Ca. While the nuclei of these nuclides all contain 40 nucleons, they contain varying numbers of protons and neutrons.[1]

The term "isobars" (originally "isobares") for nuclides was suggested by Alfred Walter Stewart in 1918.[2] It is derived from the Greek word isos, meaning "equal" and baros, meaning "weight".

What is the importance of isobars?

Isobars are lines that connect points of equal atmospheric pressure on weather maps. Isobars are similar to height lines on a geographical map, and they are drawn so that they can never cross each other. Meteorologists use isobars on weather maps to depict atmospheric pressure changes over an area and to make predictions concerning wind flow.

Isotopes:

Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties. Every chemical element has one or more isotopes.

Hope it helps you.

Answer 2

ISOBARS :-

Isobars are atoms of different elements having same mass number .

For example :- $Ar \: \frac{40}{18} \: and \: Ca \frac{40}{20}$

ISOTOPES

Atoms of the same elements having different number of neutrons ( or mass number ).

• Example :- Protium, Deuterium , tritium.
• Tritium is radioactive.
• Carbon dating method uses C14, an isotope of C12.
