The Cl atom gains an electron from another atom, and electrons carry a 1- charge.
The Cl atom does this because it has 7 outer shell electrons, which isn't very stable, while an outer shell of 8 electrons is stable.
Chloride or Cl- is the anion (Negative ion) formed by a single chlorine atom that gains an extra electron.
No, Cl- is not an atom. It is an ion. Cl- represents a chlorine atom that has gained an electron, giving it a negative charge.
Ionic bond because losing 1 electron makes the atom a +1 ion; gaining 1 electron makes the atom a -1 ion. A Cl atom attracts the outer shell electron of a Na atom forming a Na^+1 ion and a Cl^-1 ion. And that is NaCl , table salt!!!!
When an atom loses electrons, it becomes a positive ion Examples: Na --> Na+ + e- Mg --> Mg2+ + 2e- When an atom gains electrons, it becomes a negative ion Examples: Cl + e- --> Cl- O + 2e- --> O2-
The ion formed by a calcium atom is called a calcium ion, which has a 2+ charge.
The ionic symbol for chloride is Cl-. It represents the chloride ion, which is formed when a chlorine atom gains one electron to achieve a stable electron configuration.
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.
A chloride ion (Cl-) has the same number of electrons as a neutral atom of chlorine (Cl). The neutral chlorine atom has 17 electrons, and when it gains one electron to form the chloride ion, it also has 17 electrons but with a 1- charge.
Na+ and Cl- ions are formed, which then results in the formation of the ionic compound NaCl.
The ion formed by an arsenic atom is As3- (arsenide ion) when it gains three electrons or As3+ (arsenite ion) when it loses three electrons.
An ions is formed when an atom gains or loses electrons.
No, the chloride ion is a single elemental ion, Cl-.
