An atom is always assumed to be neutral unless otherwise denoted. A neutral atom can become positively charged, for example, with a charge of 2+ when it loses 2 electrons (oxidation) to another atom in a redox reaction. The other atom, in turn was reduced (it's oxidation state or number), or gained electrons and subsequently, a negative charge.

If an atom gives up 2 electrons, it will become a 2+ charged ion.

Easy -- loss of two electrons to form a +2 charge.
Examples are elements like calcium and barium in aqueous solution. Both form ions with charge +2 in solution.

By losing two electrons. Some elements have a tendency to lose these electrons so they will have an outer shell similar to noble gases, which is a very stable structure.
