It becomes an ion.
Chlorine atoms have 7 outermost electrons and need to gain an electron to achieve the stability of a full valence shell.
Ion. Any atom that loses or gains an electron becomes an ion.
There are 7 electrons on the valence shell. Chlorine requires one electron to make it complete and the ion would therefore be Cl- (one minus charge)
A chlorine atom has 7 valence electrons, as it is in group 17 of the periodic table. A chloride ion has 8 valence electrons, as it gains an additional electron to achieve a full octet and a stable electron configuration.
A sodium atom has 1 electron in its valence shell, while a chlorine atom has 7 electrons in its valence shell. When sodium reacts with chlorine to form sodium chloride, the sodium atom loses its 1 electron to achieve a stable octet configuration, while the chlorine atom gains this electron. The resulting sodium chloride molecule has 8 electrons in the valence shell of the chlorine atom.
A negatively charged "ion".
The valence of a monoatomic chlorine ion is 1 and its charge is -1.
Chlorine atoms have 7 outermost electrons and need to gain an electron to achieve the stability of a full valence shell.
If a chlorine atom gains a valence electron, it becomes a negatively charged ion known as a chloride ion (Cl⁻). Conversely, if it were to lose a valence electron, which is less common for chlorine, it would become a positively charged ion, but this scenario is unlikely due to its high electronegativity. Thus, the most common ion formed by chlorine is Cl⁻ when it gains an electron.

an ion. If a chlorine atom gains an electron, it becomes a negatively charged chloride ion (Cl-) and if it loses an electron, it becomes a positively charged chlorine cation (Cl+).
Ion. Any atom that loses or gains an electron becomes an ion.
When sodium bonds with chlorine to form table salt (sodium chloride), the sodium's valence electron is transferred to chlorine. This transfer results in sodium losing one electron to achieve a full outer shell of electrons (achieving a stable electron configuration), while chlorine gains one electron to also achieve a full outer shell. This transfer of electrons creates an ionic bond between the two atoms.
If a chlorine atom gains a valence electron, it becomes a negatively charged ion known as a chloride ion (Cl⁻). Conversely, if it loses a valence electron, it would become a positively charged ion, although this is less common for chlorine. These charged particles are called ions, which result from the gain or loss of electrons.
There are 7 electrons on the valence shell. Chlorine requires one electron to make it complete and the ion would therefore be Cl- (one minus charge)
