Explanation:
The important quantum-mechanical concepts associated with the Bohr model of atom are :
1. Electrons are nothing but particles that revolve around the nucleus in discrete orbitals.
2. Energy is associated with each orbital is quantised. Meaning electron in each shell will have energy in multiple of a fixed quanta.

The answer is a. Chemical change.
An increase in thermal energy, changes the state of matter from solid to liquid to gas.
The mass of one atom of Carbon is 2.0×10^−26 kg.
The mass of the period mark(kg)= 1.0x10^-7 kg.
# of carbon atoms=1x10^-7/2x10^-26
# of carbon atoms= 5x10^-34
