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.
I would assume that the object was positively charged if it gained electrons, because the charge tries to balance itself and since electrons are negatively charged the object would attract negative energy if it was positively charged
No, when an object gains electrons, it develops a negative charge. Electrons have a negative charge, so adding them to an object results in an overall negative charge.
When an object gains more electrons than protons (has a surplus of electrons), the object becomes negatively charged.
An object's net charge becomes positive if it loses electrons because it has an excess of positive protons relative to negative 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.
An object becomes positively charged if it loses electrons. This is because electrons have a negative charge, so the less of them there are in an object, the stronger the positive charge is.
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.
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.
A positive 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.
An object's net charge becomes positive if it loses electrons because it has an excess of positive protons relative to negative electrons.
The direction of the flow of electric current. In a positive object, electrons flow to it because it has an abscence of negative charge (aka electrons). In a negative object, it has an abundance of negative charge (electrons) so electrons flow away from it.
It has a positive charge.
positive
The nucleus of an atom has both electrons and neutrons. An atom that has a positive charge means that the atom has fewer electrons than it has protons.
