Question

Match the column :

Postulates	Theory
p) Atoms are divisible into three subatomic particles	i. Dalton's atomic theory
q) Discovery of the nucleus ( central positive charge)	ii. Modern atomic theory
r) Atoms are indivisible	iii. Rutherford
s) Position of the electron	iv. Neils Bohr

• A. $p\to ii,q\to iii,r\to i,s\to iv$
• B. $p\to i,q\to ii,r\to iv,s\to iii$
• C. $p\to iii,q\to iv,r\to i,s\to ii$
• D. $p\to iv,q\to i,r\to ii,s\to iii$

Answer 1

The correct option is A $p\to ii,q\to iii,r\to i,s\to iv$

1) According to modern atomic theory atoms are divisible into three subatomic particles that is electron, proton and neutron.

2) Rutherford explain the concept of central positively charged nucleus by his experiment.

3) Dalton had given the postulate of atomic theory according to that atoms are indivisible.

4) Neil Bohr explained the concept of orbit in which electron reside.
