Is covalent gained lost or shared electrons?

Answer 1

Depends on the atom, remember that metals want to loose all valence electrons and non-metals want to gain electrons so that it has 8 valence electrons (similar to noble gases)

For example Al (Aluminum) is in group 3, it's a metal so it will lose 3 valence electrons making it have a charge of +3 or AL3+.

Another example, F (Florine) has 7 valence electrons, it's a non-metal so it will gain 1 to become stable, making it have a charge of -1 or F1-.

Hope this helps Ya! :-P

Answer 2

When two or more atoms react they "want" full outer shells. Which vertical group the atom is in, tells you how many electrons it has in the outer shell. Let's use potassium and chlorine.

Potassium is in group 1, so it has only 1 electron in the outer shell. Chlorine is in the halogen group, the group 1 line from the right. It has 7 electrons in the outer shell, and that shell has a capacity of 8 electrons. This means that Chlorine needs 1, and Potassium has 1 more than it needs. In a reaction with these, Potassium would give the electron in the outer shell, the valence electron, to the Chlorine atom, and we would end up with Potassium chloride (KCl).

Lets say we had for instance Calcium instead of Potassium. Calcium is in group 2, so it has 2 more valence electrons than it needs. If Calcium reacted with Chlorine we would need 2 Chlorine atoms. Calcium would give 1 electron to each Chlorine, and we would end up with Calcium chloride (CaCl2).

I hope this information could help :) Just post a message on my message board if there's anything else you want to know.

Answer 3

In a covalent bond, atoms share electrons to achieve a full valence shell and form a stable molecule. Each atom contributes equally to the shared pair of electrons, leading to a more stable structure. Covalent bonds are formed through the sharing of electrons rather than gaining or losing them.

Answer 4

covalent bonds do not gain or lose electrons, they share electrons. Ionic bonds will lose or gain electrons

Answer 5

Ionic bond; a covalent bond is formed when atoms share electrons. After ionic bonding, they are called ions instead of atoms.

Answer 6

While forming covalent bonds, the bonding atoms share electrons symmetrically or asymmetrically, however, no ions are formed.

Answer 7

An ionic bond.

Answer 8

ionic bonds
