Named after this guy who proposed that only valence electrons are involved in chemical bonding .

are generally hard but brittle.

Nonmetal atoms tend to _______electrons to achieve a noble gas configuration.

Nonmetal atoms have tendencies to attract shared electrons toward themselves. This property is called

bonding electron shared equally between 2 atoms

Bonding electron shared unequally between 2 atoms

- generally soft because the atoms are attracted by relatively weak covalent bonds.

- aqueous covalent solutions do not conduct electricity because they have no mobile charged particles.

- have lower melting and boiling point than ionic compounds

The energy levels are also called

is the way which electrons are arranged in the electron shells of the atom.

It describes the orientation of each orbital in space with the values dependent on the value of angular momentum quantum number.
