1.	Types of atomic species .
Answer» Types of atomic species Isotopes : Atoms of same element having same atomic number but different mass number. For example, isotopes of Hydrogen are ₁¹H, ²₁H, ³₁H Isobars : Atoms of different elements having the same mass number but different atomic number, e.g., ⁴⁰₁₈Ar, ⁴⁰₁₉K, ⁴⁰₂₀Ca Isotones : Atoms of different elements which contain the same number of neutrons. e.g., ¹⁴₆C, ¹⁵₇N, ¹⁶₈O Isoelectronic Species : Atoms or ions containing the same number of electrons. For example, N^3- , O^2- , F^- , Na⁺ , Mg²⁺ , Al³⁺ and Ne, having 10 electrons each are isoelectronic

Types of atomic species

Isotopes : Atoms of same element having same atomic number but different mass number. For example, isotopes of Hydrogen are ₁¹H, ²₁H, ³₁H
Isobars : Atoms of different elements having the same mass number but different atomic number, e.g., ⁴⁰₁₈Ar, ⁴⁰₁₉K, ⁴⁰₂₀Ca
Isotones : Atoms of different elements which contain the same number of neutrons. e.g., ¹⁴₆C, ¹⁵₇N, ¹⁶₈O
Isoelectronic Species : Atoms or ions containing the same number of electrons. For example, N^3- , O^2- , F^- , Na⁺ , Mg²⁺ , Al³⁺ and Ne, having 10 electrons each are isoelectronic
