Question

Establish the relationship between atomic number,mass number,isotopes isobars,and valency of atoms

Answer 1

Answer:

atomic no. is the no. of protons in the atom.

atomic mass is the molecular mass of that atom.

isotopes of the same element have same atomic no. same chemical properties but different atomic mass no.

Answer 2

Atomic number — Gives the number of protons (Z)

Mass number — Gives the number of protons and neutrons (A)

Isotopes — When atoms of the same element have the same number of protons (Z) but the different number of neutrons (s) such atoms are called isotopes.

Isobars — When atoms of the different elements have the same mass number (A) but the different atomic number (Z) such atoms are called isobars.

Valency — It is the combining capacity of an atom.
