Sodium, like other metals, does not gain electrons, it loses electrons. Normally a sodium atom would lose only one electron in order to reach a stable electron configuration, becoming the Na+1 ion.
Nitrogen gains 3 electrons, oxygen gains 2 electrons, sulfur gains 2 electrons, and bromine gains 1 electron when forming ions.
An atom that loses or gains electrons is called an ion. When an atom loses electrons, it becomes positively charged and is called a cation. When an atom gains electrons, it becomes negatively charged and is called an anion.
Oxygen gains 2 electrons to become an oxide ion (O2-).
There are a total of 11 electrons in Sodium.
Oxygen gains 2 electrons to achieve a full valence shell with 8 electrons. This gives oxygen a stable electron configuration similar to the noble gas configuration.

Yes it gains two electrons, because it already has 6 valence electrons..it gains two to make it an even 8 (because of the Octet Rule). Since it gains two electrons it makes it O^-2

The element is sulfur with 16 electrons. It gains two electrons to form sulfide ion which has 18 electrons as that of argon.
All of 11 electrons in sodium are in different electron orbitals: 2 electrons are in 1s orbital, 2 in 2s, 6 in 2p and 1 in the 3s orbital. (This last one is the so-called valence electron)
In a sodium atom, there are 2 electrons in the innermost shell. The first shell can hold a maximum of 2 electrons. Sodium has an electron configuration of 2-8-1, so the inner shell contains 2 electrons.
Two electrons
surely i don't know sodium atom which can be gained 2 electrons but anyway i thought the answer is Na+2
Sodium (11Na) has 2 electrons in the first (1st), 8 electrons in the second (2nd) and one in the (3rd) level.
