When different elements (different types of atom) react and combine to form a compound (new substance) chemical bonds must be formed to keep the atoms together. Once these atoms are joined together its usually difficult to separate them. The atoms can join together by sharing electrons in what is known as a covalent bond. Or, they can transfer or accept electrons to form positive and negative.

Ionization is the process in which one or more electrons are removed from an atom or molecule. The charged particle that results is called an ion.

Critical potentials were measured as the differences between two retarding potentials—the smallest retarding potential preventing the entrance of the electrons.

so the higher the difference in EN the more likely it is ionic. Salts, eg NaCl, are ionic. In pure covalent bonds the electrons shared are shared equally between the two atoms. The smaller the.

These two-valence-electron atoms have transitions of electrons between energy levels that, as in alkali atoms, can be used.

These graphs illustrate why water (H2O) is blue, while "heavy" water (D2O) is colorless.The graph gives the visible and near-IR spectrum of H2O and D2O at room temperature. The absorption below 700 nm in wavelength contributes to the color of water (the blue graph).

The electrons are so much lighter with respect to mass to the other particles that they are not even considered when determining atomic masses of the elements. When determining the atomic mass though,
