It would be the ion fluoride, formed when a fluorine atom gains an electron. None of the elements on the Periodic Table are charged in their elemental state.
The element within period 2 with the greatest nuclear charge is neon. This is because neon has more protons in its nucleus compared to the other elements in period 2, giving it the highest nuclear charge.
Lithium is in the first period of the periodic table. It is the first element in the alkali metal group.
The charge of Li₂X depends on the identity of the element X. Lithium (Li) has a +1 charge, so in the compound Li₂X, two lithium ions contribute a total charge of +2. To balance this, the element X must have a charge of -2. Therefore, if X is an anion with a -2 charge, such as oxide (O²⁻) or sulfide (S²⁻), then the overall charge of the compound Li₂X is neutral.

The lightest element that is in period number 2 is lithium. Lithium is also the solid that is the least dense.
The element within period 2 with the greatest nuclear charge is neon. This is because neon has more protons in its nucleus compared to the other elements in period 2, giving it the highest nuclear charge.
Helium is a period 1 element.
The element with 2 electrons and a charge of -1 is helium. It typically has a charge of 0, but can gain an extra electron to have a -1 charge.
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.
Since Li is a group 1 element with a charge of +1, and there are 2 Li atoms, the overall charge of Li2 in the compound is +2. Therefore, in order for the overall charge of Li2X to be zero (since it is a neutral compound), X must have a charge of -2.
Sodiumis in group 1 and its cation is charge +1. Calcium is in group 2 and the cahrge on its cation is +2. etc.
The element phosphorous (P) is located in group 15, period 2.
The element in period 2 with the most mass is Neon (Ne).
Lithium is in the first period of the periodic table. It is the first element in the alkali metal group.
An element you have a +2 charge It is had lost electrons. It would have to lose the same number of electrons that its positive charge is. So it would have lost 2 electrons.
The charge of Li₂X depends on the identity of the element X. Lithium (Li) has a +1 charge, so in the compound Li₂X, two lithium ions contribute a total charge of +2. To balance this, the element X must have a charge of -2. Therefore, if X is an anion with a -2 charge, such as oxide (O²⁻) or sulfide (S²⁻), then the overall charge of the compound Li₂X is neutral.
O2 is a diatomic element(as are H, N, F, Cl, Br & I), I believe the charge for O2 is (2-), H=1+, N=3-, F-I=1-
