Electrons are present in distinct energy levels around the nucleus.
Explanation:
About energy quantization at the atomic level, electrons are present in distinct energy levels around the nucleus.
This was the view from Bohr's model of the atom based on the quantum mechanics.
- His model was based on the premise that electrons can move round the nucleus only in permissible orbits or energy levels.
- An electron in an energy level has a definite amount of energy associated with it at that level.
- For electrons to undergo transition from one level to another, they gain or lose energy.
- This is the concept of the energy quantization of atomic level.

Answer: C is False and the rest is true
Explanation:
iii)-The temperature sensor is placed near the bottom of an aluminum heating block, closer to the heater than the sample, and is likely to read lower than the actual melting point of the sample. —— FALSE
