(i) Atomic number
(ii) Mass number
(iii) Isotopes
(iv) Isobars
Give any two uses of isotopes.
​

Answer 1

Answer:-

(1) Atomic Number :- Atomic Numbers can be define as the number of protons present in the Nucleus of an Atom. It is denoted by "Z".

Ex:- Number of Protons in Carbon is 6. Hence, It Atomic Number is 6.

(2) Mass Number:- Mass Number can be define as the sum of Number of Protons and Number of Neutrons in the Nucleus of an Atom. It is denoted by "A".

Ex:- Number of Protons in Carbon is 6 & Number of Neutrons in Carbon is 6.

Hence, Mass Number is 12.

(3) Isotopes :- Isotopes are define as the Elements having Same Atomic Number but different Mass Number.

(4) Isobars:- Elements having Same Atomic Mass but different Atomic Number are said as Isobars.

USES OF ISOTOPES:-

☆Used as tracers for diagnostic purposes.

☆ Used as Medicine.
