As2-
An ions is formed when an atom gains or loses electrons.
Everything in Group 5 except bismuth e.g. nitrogen, phosphorus, arsenic, and occasionally antimony
The symbol for an arsenic ion is As3+.
A one-atom ion is called a monatomic ion. It is formed when an atom gains or loses electrons, resulting in a net positive or negative charge.
Anion
The ion formed by a calcium atom is called a calcium ion, which has a 2+ charge.
The ion formed by a fluorine atom is called a fluoride ion, which has a charge of -1. It is formed when a fluorine atom gains an electron to achieve a full outer electron shell.
Arsenic becomes an ion by gaining or losing electrons. It can either gain three electrons to form the As3- ion (arsenide ion) or lose three electrons to form the As3+ ion (arsenite ion), depending on the reaction conditions.
The arsenic ion with a -3 charge has gained 3 electrons, giving it a total of 3 more electrons than the neutral arsenic atom. Arsenic typically has 33 electrons in its neutral state, so the arsenic ion with a -3 charge would have 36 electrons.
An ions is formed when an atom gains or loses electrons.
The ion given is formed when the neutral arsenic atom gains three electrons.
