False. Remember, normal atoms are neutral because they have equal numbers of positive protons and negative electrons. Atoms become ions when they either gain or lose electrons (the number of protons stays the same).
If you add electrons, which are negative, to a neutral atom they will then outnumber the positive protons and a negative ion is formed. Lilewise, if you take negative electrons away from a neutral atom, the positive protons will outnumber the remaining electrons and the ion will be positive.

False. An electron has a negative charge, so if an atom gains an electron it gains a negative charge and becomes a negative ion. You may be getting confused by the fact that negatively-charged ions, such as a chlorine atom that has gained an electron, are drawn towards places where there are positive charges.

no it is kind of confusing but if you add electrons u get a negative ion and if you take them away u get a postive ion.

false, and if that isn't obvious you have a lot of catching up to do.
