Alkali metals and alkaline earth metals will form ions (by losing 1 and 2 electrons respectively) with noble gas electron configuration.
If alkali metals loses one electron, they achieve the electronic configuration of the nearest noble gases.
All halogens have 7 valence electrons. They gain one electron and achieve noble gas electronic configuration
The stable ions of all the elements except the Transition metals, Actinide, and Lanthanide series (that is the d and f block elements) form stable ions that are isoelectronic to a nobel gas by gaining or losing electrons in order to achieve an s2 p6 stable octet. For example, sodium will lose one electron to have the same electron configuration as neon, while nitrogen will gain three electrons to become isoelectronic to neon.
Ions that are formed when metals gain electrons are called anions. This process allows metals to achieve a stable electron configuration by filling their outermost energy level, similar to noble gases.
It accepts one electron.

The "Noble gas electron configuration," or the condensed electron configuration, for F is [He] 2s2 3p5.
The element that will have a noble gas configuration after donating one electron to fluorine is lithium. By donating one electron, lithium achieves the electron configuration of helium, which is a noble gas.
The pseudo noble-gas electron configuration has the outer three orbitals filled, the s, p and d- s2p6d10 (18 electrons total) and so is fairly stable. Elements that attain this electron configuration are at the right side of the transition metals (d-block). Br-, I-, Se2-

Chlorine will have a noble gas configuration by accepting one electron from a sodium atom to form an ionic bond. This results in chlorine gaining a full outer electron shell, similar to the noble gas configuration of argon.
It accepts one electron.
Non-metals become negatively charged ions, also known as anions, after accepting an electron. This electron addition allows them to achieve a stable electron configuration similar to that of noble gases.
Metals , generally, have electronic configuration: with outermost electron having 1,2 or 3. Since, they can easily attain noble gas configuration to attain stability; they readily loose electron.
A noble gas electron configuration involves representing an element's electron configuration by using the electron configuration of the nearest noble gas preceding it in the periodic table, followed by the remaining electron configuration for that element. For example, the noble gas electron configuration for sodium (Na) is [Ne] 3s¹, where [Ne] represents the electron configuration of neon leading up to sodium.
