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.
Nitrogen gains 3 electrons, oxygen gains 2 electrons, sulfur gains 2 electrons, and bromine gains 1 electron when forming ions.
The element with 10 electrons in its neutral state is neon (atomic number 10). When it forms an anion with a 2- charge, it gains 2 electrons to have a total of 12 electrons, taking on the electron configuration of the noble gas, argon.
The same number of valence electrons as xenon.
If an element gains electrons, it has a negative oxidation number. The oxidation number is determined based on the number of electrons gained or lost by an atom in a compound. The rule is that in ionic compounds, the oxidation number of an element is equal to the charge it would have if it were an ion.
Oxygen gains 2 electrons to become an oxide ion (O2-).
The element is sulfur with 16 electrons. It gains two electrons to form sulfide ion which has 18 electrons as that of argon.
Nitrogen gains 3 electrons, oxygen gains 2 electrons, sulfur gains 2 electrons, and bromine gains 1 electron when forming ions.
The ion would have two fewer negative charges so the ion would be more positive by +2

A metalloid :)

In the reduction process, electrons are typically used to reduce an element by gaining or accepting the electrons. The element being reduced gains electrons, thereby decreasing its oxidation state.
Oxygen gains 2 electrons to become an oxide ion (O2-).
If a neutral atom gains one or more electrons, then it will have a negative change. If a positive atom gains electrons, it will have an increase in change, but the charge may be negative, neutral, or positive based on the initial charge and number of electrons gained. The process in which an atom gains electrons is known as reduction.
The charge of an ion formed by an element on the periodic table is determined by the number of electrons gained or lost by the element. This charge can be positive or negative, depending on whether the element loses or gains electrons.
Oxygen is the period 2 element most likely to form an ion with a charge of minus 2 because it readily gains two electrons to achieve a stable electronic configuration.
