A cation is a positively charged particle formed by the loss of one or more electrons from an atom.
Atoms are neutral species containing protons and neutrons in the nucleus and electrons in the orbitals (or shells). Ions are formed when an atom gains or loses electrons. If an atom gains electrons, then negatively charged ions called anions are formed. If an atom loses electrons, then positively charged ions called cations are formed.
Anion. An anion is formed when a neutral atom or molecule gains one or more electrons, resulting in a negative charge due to an excess of electrons compared to protons.
If a neutral atom gains one or more electrons, then it will have a negative change. If a positive atom gains electrons, it will have an increase in change, but the charge may be negative, neutral, or positive based on the initial charge and number of electrons gained. The process in which an atom gains electrons is known as reduction.
When a particle loses electrons, it becomes positively charged due to having more protons than electrons. Conversely, if a particle gains electrons, it becomes negatively charged as it has more electrons than protons. This imbalance in charge leads to the formation of a charged particle.

Negatively charged anions are formed.
An electron has a negative charge, so if a neutral atom gains an electron, it becomes a negative ion. A negative ion is called an anion.
The ion given is formed when the neutral arsenic atom gains three electrons.
The fluoride ion (F-) contains more electrons than the sodium ion (Na+), as fluoride has 10 electrons in its neutral state whereas sodium has 11 electrons in its neutral state. When fluorine gains an electron to become fluoride, it has one more electron than sodium.

The particle in question gains or loses electrons.
A neutral atom that subsequently gains or loses one [or more] electrons is called an ion. If it gains an electron [or electrons] it will have a negative charge. If it loses an electron [or electrons] it will have a positive charge.

This atom become an anion.
When a negatively charged object touches a neutral object, electrons transfer from the negatively charged object to the neutral object, causing the neutral object to gain electrons. This results in the neutral object becoming negatively charged.
If a neutral atom gains one or more electrons, then it will have a negative change. If a positive atom gains electrons, it will have an increase in change, but the charge may be negative, neutral, or positive based on the initial charge and number of electrons gained.
