• Metal atom loses electron(s) to nonmetal atom

• Two nonmetal atoms share electrons

• Hydrogen attracts an electronegative atom electrostatically

• Positive metal ions attract conducting electrons

It is simply a combination of two or more atoms connected by a chemical bond which forms the smallest unit of substance that retains the composition and the properties of substance

Atoms in molecules are held together by __________.

If the difference in the electronegativity is too large, the electrons might become so polarized that they will be transferred instead of being shared.

It is a measure of an atom’s ability to attract and hold onto electrons.

Covalent Molecular Substances have low melting and boiling points due to weak attractive forces between the particles.

• TRUE

• FALSE

Low densities indicate that the particles are NOT COMPACT.

• TRUE

• FALSE
