Lead is soft and malleable, and has a relatively low melting point. The electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. Tellurium is a brittle, mildly toxic, rare, silver-white metalloid.

For example, silicon has nine possible integer oxidation states from −4 to +4, but only -4, 0 and +4 are common oxidation states. If there are too many or too few neutrons for a given number of protons, the resulting nucleus is not stable and it undergoes radioactive decay. For stable elements, there is usually a variety of stable isotopes.
