What type of chemical bond involves the sharing of a pair of electrons by two atoms in a molecule.
Over [174]

Answer:

Covalent bond.

Explanation:

There are two kinds of chemical bonds: covalent bonds and ionic bonds.

  • A covalent bond is formed when two atoms share a pair of electrons (two electrons for each bond.)
  • Ions are formed when one atom transfers an electron to another. Ionic bonds refer to the attraction between ions of opposite electric charges.

In this example, since the atoms are sharing atoms, the chemical bond between them would be a covalent bond.

When two carbon atoms are joined by a double bond, how many electron pairs are shared between the two carbons
NikAS [45]

Answer:

Two (2) electron pairs

Explanation:

The sharing of electron pairs by atoms forms a type of bond called COVALENT bond. Atoms that form covalent bonding (share electrons) do so in order to fill their outermost electron shells, hence, gain chemical stability.

However, when two atoms like carbon share TWO PAIRS of electrons with each other, a DOUBLE BOND is formed. An example is the double bond formed in Ethylene (2HC=CH2). A total of four valence electrons (a pair from each carbon) are shared between the two carbon atoms.
