Question

Question 1: Write any two observations which support the fact that atoms are divisible.

Answer 1

‘Atoms are divisible' is supported by the following facts:

(i) Formation of ionic compounds is possible due to the formation of ions which involves the transfer of electrons.

(ii) Presence of isotopes of the same element is possible due to the difference in the number of neutrons.

Above observations show that an atom is formed by different particles such as electrons, protons and neutrons, i.e., an atom is divisible.
