Answer:

Explanation:

In the Bohr model of the atom, electrons are arranged in energy levels. The electrons in the lowest energy levels are nearest to the nucleus. An electron may move from a lower to a higher energy level by absorbing energy that is equal to the difference between the energies of the higher and lower energy level.

The potential energy of all electrons inside the atom have negative values and an electron which is infinitely far from the nucleus has an electrostatic potential energy of zero.

Energy is absorbed when an electron is removed from the atom (ionization). Hence the process is highly endothermic. Therefore it is false to say that "Energy is released when the electron is ejected from the atom."

Substance A is added to water. After it is added, hydrogen ions are produced and accumulate in the

Substance A is an acid.

Substance B is a group of hydronium ions.

Explanation:

From the description above, we can deduce that substance A is an acid whereas substance B is a group of hydroxonium ions.

An acid can be defined as a substance that produces hydrogen ions in solution.

Acids interacts with water to produce excess hydroxonium ions, H₃O⁺ in an aqueous solution.

The hydroxonium ions results from the chemical bonding between oxygen of water molecules and protons released by the ionization of the acid:

HCl + H₂O → H₃O⁺ + Cl⁻
