This article is about the exonerated physician. For the filmwriter and actor, see Sam Shepard. Samuel Holmes Sam Sheppard, D.O. ((1923-12-29)December 29, 1923 â April 6, 1970(1970-04-06)) was a Bay Village, Ohio neurosurgeon initially convicted for the 1954 murder of his wife, Marilyn Reese Sheppard. The case was highly controversial from the beginning, with extensive and prolonged nationwide media coverage.
A covalent bond is a chemical bond between two nonmetals (two metals cannot covalently bond) in which electrons are shared, while an ionic bond is a chemical bond between a me â¦ tal and a non metal due to the attraction between oppositely charged ions. 13 people found this useful.

They are lattices composed of oppositely charged ions. Ionic solids tend to have high melting points (high generally being higher than metallic but lower than covalent). Because the electrons in ionic solids are localized (in the ions) these solids tend to be stiff and brittle like covalent solids.As solids they do not conduct electricity (again because of the localize electrons). However, they do conduct electricity as liquids (or when dissolved in water) since then the ions can move.ecause the electrons in ionic solids are localized (in the ions) these solids tend to be stiff and brittle like covalent solids. As solids they do not conduct electricity (again because of the localize electrons).
