Al2O3
A lone pair is elements in a chemical reaction that are not used in the reaction.
A roman numeral in parentheses follows the name of the metal... apex
the shared valence electron pairs repel each other.
molarity
C.A molecule that has a symmetrical shape will be a nonpolar molecule.
A nonpolar covalent bond involves an even sharing of electrons.
C.The charges on the ions
Helium has the highest first ionization energy and francium has the lowest first ionization energy.
The lone pair repels the electrons of the adjacent bonds more so than does a bonding pair of electrons, so thus alters the molecular geometry of the molecule.
a force acting between two different molecules
