Question

Write the five differences between isobars and isotopes in a tabular form.

Answer 1

Representation of an atom:

• The mass number is the sum of the number of protons and neutron numbers in an atom.
• The atomic number is equal to the number of protons in an atom.

Isotopes	Isobars
Isotopes are those atoms that have the same atomic number but a different mass numbers.	Isobars are those atoms that have the same mass number but different atomic numbers.
Isotopes are atoms of the same element.	Isobars are the atoms of different elements.
Isotopes have the same number of protons but the different number of neutrons.	The number of electrons in isobars is different.
Isotopes have the same chemical properties.	Isobars have different chemical properties.
The physical features of isotopes differ from each other.	Isobars have plenty of physical traits in common.
