Answer:
Energy of an electron is quantinized means the electrons can possess only specific individually separated values.
These energy levels are stable and are stationary along with different energy value. The electron remains in the state until energy is absorbed or released.
The electrons absorb energy when it moves from lower energy state to higher energy state. The electrons lose energy when it moves from higher energy state to lower energy state and thus emit radiations corresponding to the energy gap and is called as quanta.
Democritus<span> first suggested the existence of the atom.</span>
Answer: adding
Explanation:
Because it takes thermal energy to power it
2Ca+O2<span>➡2CaO
You need to balance it by adding a 2 as the coefficient on the Ca, then put 2 on the products side
