Question

answers in three- four sentences: draw the preliminary structures of the molecules of water methane and ammonia where the atoms are held by covalent bonds​

Answer 1

Answer:

Covalent bonds, which hold the atoms within an individual molecule together, are formed by the sharing of electrons in the outer atomic orbitals.

The distribution of shared as well as unshared electrons in outer orbitals is a major determinant of the three-dimensional shape and chemical reactivity of molecules.
