what happens to valence electrins when a chemical bond forms between atoms?

Answer 1

Valence electrons are either shared or transfered. Ionic bonds occur between non-metals and metals (elements on the right side of the"zig zag" line and elements on the left side of the line). In an ionic bond, the electrons are transferred from the metal to the nonmetal. For example, NaCl. Na loses an electron to form a +1 ion, and Cl gains an electron to form a -1 ion. These two are bonded because of their oppositely charged electrostatic charges. In covalent bonds, which occurs between to nonmetals (e.g.: N and O), the valence electrons are shared between the atoms.

Answer 2

Its because of reality of their Valence Electrons. If an atom of an element has 4 valence electrons, it ought to both benefit or percentage 4 to grow to be solid. An atom both needs 0 or 8 Valence electrons to be solid. via potential of ways, Valence electrons are the electrons on the outer maximum potential element.

Answer 3

some of the valence elctrons can be shared !
For C-C bond (4 valence electrons each)
2 electrons -> covalent bond
4 electrons-> double bond
6 electrons-> triple bond

Answer 4

They are either transferred from one atom to another(ionic bonding) or become shared between the atoms(covalent bonding).
