Energy state, also called Energy Level, in physics, any discrete value from a set of values of total energy for a subatomic particle confined by a force to a limited space or for a system of such particles, such as an atom or a nucleus. …
Q. Why is energy of 1s electron lower than 2s electron?
An electron in a 1s orbital is of lower energy than one in a 2s orbital because it spends more of its time close to the atomic nucleus.

Q. What is quantised energy?
The quantization of energy refers to the fact that at subatomic levels, energy is best thought of as occuring in discreet “packets” called photons. The red and blue photons are therefore “quantized” just as dollar bill denominations are “quantized”. Each photon contains a unique amount of discreet energy.
Q. What if Planck’s constant was zero?
if Planck constant is zero, both momentum and position can be known simultaneously. if Planck constant is zero, all quantum behavior will become classical behavior, where energy will become continuous, momentum will become zero (which means it is known exactly) and etc.
Q. How big is Planck’s constant what if Planck’s constant was zero?
If Planck’s constant were zero, all the commutators would be zero. If the commutators are all zero, all operators commute. If all operators commute then there would be no uncertainty principle. Because Planck’s constant is so close to zero, for a long time the human race was unaware of quantum mechanics.
Q. Would it be possible to determine the position and momentum of an electron simultaneously and accurately if the value of Planck’s constant is zero?
Heisenberg’s uncertainty relation tells us that the product of the uncertainty in position and momentum is actually proportional to Planck’s constant. If Planck’s constant is zero, this uncertainty is zero. So there’s no problem in determining the position and momentum of an electron(or anything else) simultaneously.
