A chlorine atom wouldn't need to lose anything, but a chlorine ion would need to lose 1
When a chlorine atom becomes a chlorine ion, it gains an electron to achieve a full outer electron shell. This results in the electron arrangement changing from 2,8,7 to 2,8,8, making it a negatively charged ion.
A chlorine atom needs one additional electron in order to become stable.
Three chlorine ions are required to bond with one aluminum ion in order to form the compound aluminum chloride. This results in a stable compound with a 1:3 ratio of aluminum to chlorine ions.
A neutral chlorine atom has 7 valence electrons and needs one more valence electron in order to be stable with an octet. A chlorine molecule consists of two chlorine atoms that have formed a covalent bond between them, so that each chlorine atom effectively has an octet of valence electrons, which makes the chlorine atoms stable. A chloride ion is a chlorine atom that has gained an electron, becoming a charged particle with a charge of 1-.
Chlorine will gain one electron in order to establish a full outer shell of electrons. Chlorine atoms have 7 valence electrons, but with one extra electron, it can establish a stable octet.
When a chlorine atom becomes a chlorine ion, it gains an electron to achieve a full outer electron shell. This results in the electron arrangement changing from 2,8,7 to 2,8,8, making it a negatively charged ion.
The metals aluminum, calcium, and potassium will give up electrons to be stable. Chlorine is a nonmetal and it will gain an electron in an ionic bond in order to be stable.
A chlorine atom needs one additional electron in order to become stable.
Chlorine's structure makes it very reactive (it is in group VII of the Periodic Table and therefore needs to gain one electron in order to become stable)!
Cl - This means that Chlorine has an extra electron, so it's negative. Chlorine already has 7 electrons and in order to be stable, it only needs one more electron.
actually valency is the combining capacity of atoms so to attain stable configuracy the lose or gain electrons for example chlorine has configuration of 2,8,1 so in order to attain stable configuracy they lose 1 electron.THIS is why we say chlorine has -1 as valency

I know sodium is one but I am still checking for the others. Someone said all but the noble gases.
A filled valence shell is a very stable electron arrangement in the outer energy level. Atoms undergo chemical reactions in order to achieve a filled valence shell, which is usually 8 electrons, but for hydrogen, helium, lithium, and beryllium it is 2 electrons.
A lone chlorine atom has 7 outer shell electrons, 1 electron short of a full outer shell of 8 electrons, which is stable. In order to achieve this full outer shell two chlorine atoms share a pair of electrons, with each atom contributing 1 electron to the pair. By sharing electrons in this manner the chlorine atoms achieve a full outer shell.
