neutral
They do not. An electron is negatively charged and an atom can only acquire a negative charge on gaining electrons.
The group 2 elements form ions with a 2+ charge. For example, Mg2+ and Ca2+. The group 16 elements form ions with a 2- charge. For example, O2- and S2-.
There's no charge within the atom of each group since there is a same number of electrons (negatively charged) and protons ( positively charged). The charge does not change unless after ionic bonding. The atomic charge changes depending on the reaction.
what changes the charge of the atom
A neutral atom will have a charge of ZERO

They are not elements, they are ions. A sulfide ion consists only of a single sulfur atom with two extra electrons, giving it a charge of -2. The sulfate ion consists of a central sulfur atom bonded to four oxygen atoms. It too has a -2 charge.
Nickel has an atomic number of 28- so if there aare only 26 electrons - 2 are missing and the ion will have a harge of 2+.
what changes the charge of the atom
An element's nuclear charge is the positive charge located in the nucleus of an atom, equal to the number of protons in the atom. It determines the element's position in the periodic table and plays a significant role in determining the atom's chemical properties and reactivity.
An atom is always neutrally charged, with equal numbers of protons and electrons. As soon as elements lose or gain electrons, they become ions.
A neutral atom will have a charge of ZERO
Carbon is an element. Elements are atoms at its simplest. A molecule is a collection of atoms connected by an electric charge.
This is an oddly stated question but I would assume you are talking about elements such as neon, argon, xenon, krypton, i.e. noble gases which are monoatomic elements. They are inert gases that, under ordinary circumstances, do not react with other elements to form compounds.
Charge refers to the electrical charge of an ion, which is the number of valence electrons gained or lost by an atom. Oxidation number, on the other hand, is a hypothetical charge assigned to an atom in a compound based on a set of rules. The oxidation number can be used to determine the charge of an ion in a compound, but it does not always represent the true charge of the atom.
