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

1 Mol

How does a hydrogen ion change into an atom?

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.


Which principal energy level change by the electron of a hydrogen atom will cause the greatest amount of energy to be absorbed?

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.


The transition of an electron from outer orbit to inner orbit involves a change in its what?

Would adding an electron to hydrogen change its mass?

no, it would change its charge not its mass.


When radiation is absorbed by a hydrogen electron the hydrogen atom changes its ground state to?

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.


How does hydrogen ion change into a hydrogen atom?

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.

What are the selection rules for hydrogen in a spectroscopic transition?

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.

What is the standard enthalpy change for a reaction in kilojoules per mole (kJ/mol)?

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 how do its density and weight change?

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.
