the atom gains or loses energy
When an electron jumps to a new energy level, it does so in discrete steps. The number of times an electron jumps to a new energy level depends on factors such as the element, its atomic structure, and external influences like temperature or electromagnetic fields. Each jump represents a change in the electron's energy state within the atom.
An electron must absorb or release a specific amount of energy, typically in the form of a photon, to move to a new energy level in the electron cloud. This process is known as electron excitation or de-excitation.
Hydrogen atom = 1 proton 1 electron Hydrogen's 1 electron occupies the lowest energy level, 1s orbital. The atom is therefore in its "ground state". When a photon of correct frequency "collides" with a electron in hydrogen's 1s orbital the energy contained in the photon is transferred to the electron. The electron then gets added energy, so it is at a higher energy state. When it reaches this higher energy state the electron jumps to the next energy level and there it starts its new orbit. Hydrogen atom is now "excited" For any other atoms it is the same thing because all atoms can undergo excitation. The only difference between hydrogen's 1 electron and other atom's many electrons is WHICH ELECTRON will be "excited"
An element's period is related to its electron configuration by indicating the energy level of its outermost electrons. Each period corresponds to a new energy level, with elements in the same period having electrons in the same principal energy level. Electron configuration describes the arrangement of electrons in these energy levels, with each period accommodating a specific number of electron shells.
First, in order for an electron in an atom to change energy levels, there must be a place for it in the new energy levels. Quantum Mechanics puts very strict rules on how many electrons can be in the same energy level. Assuming there is a place for it, then it is very likely to move into a lower energy level. It is not possible for it to move into a higher energy level unless something from the outside comes in and knocks it up. There is no way to predict when an electron will drop down into a lower energy level. When something like a photon comes in from the outside and knocks the electron into a higher level, it usually drops back down pretty quickly, but not necessarily.

It would release energy. It had to absorb it in order to get from 2 to 3. Law of conservation of energy says it must now release it to fall back.
Energy is either absorbed or released. If the electron goes from a high energy orbital to a lower energy one, a photon is emitted. When a photon is absorbed, the electron goes from low energy to high.
An electron emits energy in the form of an x-ray (a photon) when its energy level in the electron cloud decreases as a result of reduction in the excitation level of the cloud. This means that the position of the electron in the cloud changes to a lower level.
It is NOT negative (for the first IE). Because Be's configuration is 1s2 2s2, we observe that it has no vacant orbital to accommodate an electron, meaning that to insert an electron, it has to go into a new sub-orbital, the higher-energy 2p. Hence, you need energy to promote this electron to a 2p level to force Be to accept it.
