Atoms that have or electrons in their valence shells tend to gain electrons to form charged ions?

Answer 1

an ion.

Answer 2

Both. Atoms on the left hand side of the Periodic Table tend to lose electrons so their outer electron shell is empty and thus the one below it is full and thus stable. These form cations. The reverse is true for atoms on the right hand side of the periodic table. They gain electrons to get a full outer energy level and become stable. These are called anions.

Answer 3

Well, every atom wants to become stable, and the only way for this to be accomplished is by either gaining or losing electrons. And yes i do mean losing electrons. The atoms want 8 valence electrons to be stable, and they with either gain electrons or lose them to resemble a noble gas. For example, Oxygen, which is a group 16 element, is closest to the noble gas Ne (neon) and will therefore gain two valence electrons to RESEMBLE neon. Since each electron has a charge of -1, the stable form of Oxygen is O-2. However, Oxygen is a diatomic element and is therefore O sub 2. Carbon and any group 14 element can either gain or lose four electrons. These are stable Ions, however, in some conditions there can be more than one different ion, and a percentage of it which can be found naturally. You can then use this to average them both and find the average ion for an element.

Answer 4

Atoms that have few electrons in their valence shells tend to gain electrons in order to achieve a stable electron configuration and form negatively charged ions called anions. This process allows them to achieve a full outer shell of electrons similar to the nearest noble gas.

Answer 5

Yes - a positively charge ion.
