A chlorine atom gains an electron when it becomes an ion. This means it has been reduced because there is a decrease in oxidation state from 0 to -1.
This is called a redox reaction. An atom that loses an electron is oxidized and an atom that gains an electron is reduced.
When a molecule of NAD+ gains a hydrogen atom to become NADH, the molecule is reduced. Reduction is the gain of electrons by a molecule, which is what occurs in this process. This is part of a redox (reduction-oxidation) reaction where one molecule is reduced (NAD+) and the other molecule is oxidized (loses electrons).
The sodium atom becomes a singly positively charged cation, and the chlorine atom becomes a singly negatively charged anion.
It becomes a negative ion.
When a potassium atom bonds with a chlorine atom, the potassium atom donates one electron to the chlorine atom. This transfer of electrons allows potassium to achieve a stable electron configuration, resembling that of a noble gas, while chlorine gains an electron to fill its valence shell. As a result, potassium becomes a positively charged ion (K⁺), and chlorine becomes a negatively charged ion (Cl⁻), leading to the formation of an ionic bond between the two atoms.
With the loss of electron a neutral atom becomes positive ion and loss of electron is known as oxidation.
calcium + chlorine yields calcium chloride oxidation means loss of electrons, it's the calcium atom the oxidizes into the calcium cation +2. the chlorine is being reduced from chlorine neutral to chloride -1 anion.
When an electron is transferred from a sodium atom to a chlorine atom, the chlorine atom becomes a negatively charged ion because it gains one electron. This negatively charged ion is known as chloride ion.

This is called a redox reaction. An atom that loses an electron is oxidized and an atom that gains an electron is reduced.
The chlorine atom becomes an ion with a larger radius when it forms an ionic bond with sodium. This is because it gains an electron and becomes a negatively charged ion, causing the electron cloud to expand.
oxidized
if a neutral atom donates an electron it will gain a positive charge. This is due to electrons having a negative charge.
When a molecule of NAD+ gains a hydrogen atom to become NADH, the molecule is reduced. Reduction is the gain of electrons by a molecule, which is what occurs in this process. This is part of a redox (reduction-oxidation) reaction where one molecule is reduced (NAD+) and the other molecule is oxidized (loses electrons).
Sodium becomes a cation and chlorine becomes an anion.
