If you mean an atom, if it gains electrons it becomes more negative, so a negative charge. If you really mean an ion, it depends on the charge of the ion.
An object's net charge becomes positive if it loses electrons because it has an excess of positive protons relative to negative electrons.
An object with a positive charge has an excess of protons compared to electrons.
When an object has a positive charge, it means that it has an excess of protons compared to electrons. This causes the object to have a net positive charge, making it attractive to objects with a negative charge and repelling other positively charged objects.
If an object has a positive charge, it has lost electrons and now has more protons than electrons. This excess of positive charge causes the object to repel other positively charged objects and attract negatively charged objects.
It does not acquire any charge, it looses negative charge (the electrons), so becomes net positive.
That depends entirely on sign of the charge. If the object gains a positive charge, then that means the object as lost electrons, since electrons are negatively charge. If the charge is negative, then the object has gained electrons. It is also possible that the charge was created by a movement in protons, which are positively charged, in which case the object may not have lost or gained electrons.
Electrons are the particles that move when an object acquires a net positive or negative charge. In the case of a positive charge, electrons are removed from the object, leaving an excess of positive charge. Conversely, in the case of a negative charge, electrons are added to the object, creating an excess of negative charge.

Electrons can move from object to object. Electrons have a negative charge. So if an object is determined to have a positive charge, then some of the electrons have moved from the object to somewhere else. Something with a neutral charge has the same number of electrons [-] and protons [+]. If electrons [-] leave, then there will be more protons, and a net positive charge. If an object gains electrons, then the object has a net negative charge.
It has had electrons removed giving it it's positive charge.

positive charge
If an object has a positive charge, it has lost electrons and now has more protons than electrons. This excess of positive charge causes the object to repel other positively charged objects and attract negatively charged objects.
Since protons have a positive charge and electrons have a negative charge, an atom with more protons than electrons would have a positive charge. Note that an atom with this kind of imbalance is known as an ion.
It does not acquire any charge, it looses negative charge (the electrons), so becomes net positive.
