Question

explain with examples i Atomic number ii mass numbers iii isotopes iv isobars. give any two uses of isotopes​

Answer 1

Answer:

The total number of protons in an athon is called its atomic number. This us represented using the letter Z

Atomic number= Number of protons = Number of electrons

Mass number= Number of protons + Number of neutrons

Atoms of the same element having the same atomic number but different mass number are called Isotipes

Eg: Carbon-14 used to determine age of fossils and prehistoric objects

Deutirium- Isotope of hydrogen used in atomic reactors

Isobars- are atoms having same mass number but different atomic number

Answer 2

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.
