covalent bond

Postby Chels Zh 1D » Sun Jul 23, 2017 3:42 pm

Is it true that covalent bond only holds TWO nonmetal atoms together by sharing electrons?

Yes, one bond can only involve two atoms. However, one atom can have more than two bonds.

Yes, it is true. Covalent bonds are formed when two nonmetals or a nonmetal and a metalloid share electrons.

Yes, this is true, and ionic bonds are between a metal and a nonmetal

It is true because non-metals do not form cations because their ionization energies are too high, so they share electrons to form covalent bonds.

A bond only involves two atoms, but a molecule with more atoms can have covalent bonds between pairs of the atoms within it.

Some examples of molecules that use covalent bonds are

Bromine (Br2)
Iodine (I2)
Nitrogen (N2)
Chlorine (Cl2)
Hydrogen (H2)
Oxygen (O2)
Fluorine (F2)

Carbon Dioxide (CO2)
Methane (CH4)
Water (H2O)
