The change in energy is -312KJ/mol.
E=2.18*10^-18[ (1/2^2)-(1/9^2) ]
=5.1884*10^-19 J/atom
Divide by 1000 to convert to Kj
=5.1884*10^-22KJ/atom
5.1884*10^-22KJ/atom x 6.022*10^23 (avo. #) atoms = -312KJ/Mol

At the transition temperature, the heat goes into causing the change in state. Once the change in state is complete, the temperature will change.
Transition metals have a variety of properties, but one of the largest is that transition metals, in most cases, don't have a set charge. Depending on what anion they are paired with, their charge will change anywhere from 1 to 7.
There are 1000 joules in 1 kilojoules. to convert kilojoules to joules you need to multiply by 1000, this means moving the decimal point three places to the right filling any gaps with zeros. 1.5 kJ becomes 1500 J.
This is a chemical change.
A hydrogen ion can change into an atom by gaining an electron. When a hydrogen ion, which is essentially a hydrogen atom that has lost its electron, gains an electron back, it will become a neutral hydrogen atom.
A transition from n=1 to n=∞ will involve the greatest amount of energy being absorbed in a hydrogen atom because the electron is moving from the lowest energy level to an infinite distance away from the nucleus. This transition is associated with the Lyman series in the hydrogen emission spectrum.

no, it would change its charge not its mass.
When a hydrogen electron absorbs radiation, it moves to an excited state. The electron jumps to a higher energy level, causing the hydrogen atom to change its ground state to an excited state.
A hydrogen ion (H+) gains an electron to become a hydrogen atom (H). This process is known as reduction, where the electron is added to neutralize the positive charge of the hydrogen ion, resulting in the formation of a stable hydrogen atom.
The electric dipole transition refers to the dominant?æeffect of the atom's electron interaction in the electromagnetic field. It is also the transition between the system energy levels with?æthe Hamiltonian.
The selection rules for hydrogen in a spectroscopic transition are based on the conservation of angular momentum. The rules state that the change in the principal quantum number (n) must be 1, and the change in the azimuthal quantum number (l) must be 1. Additionally, the change in the magnetic quantum number (m) must be 0 or 1. These rules determine which transitions are allowed in the hydrogen atom's spectrum.

The standard enthalpy change for a reaction is the amount of heat energy absorbed or released in kilojoules per mole (kJ/mol).
When a hydrogen atom loses its electron, its density remains the same because the mass of the electron is much smaller compared to the mass of the proton in the nucleus. However, the weight of the hydrogen atom decreases since weight is a measure of the force of gravity acting on the object, which is determined by the mass of the object.
transition is a transformation of a mater. for example in politics transition is change from one government to the next.
