Answer: Electrons are lost or gained to produce anions and cations

Ionic compounds are formed from elements that have large electronegativity differences. Neutral atoms with fewer than four electrons donate them to the neutral atoms with more than four electrons. This produces very strong bonds, producing hard, brittle compounds.

Answer: calcium

The calcium compound that is a structural component of bone is hydroxyapatite, sometimes called hydroxylapatite.

Answer: cyanide

Cyanide acts like carbon monoxide, which bonds to blood cells more strongly than oxygen. This kills the victim by hypoxia, the lack of oxygen to the cells.

Answer: nitrate

All nitrates are soluble in water. The charge on the nitrate ion is minus one. Since each oxygen has a negative two charge, the valency of the nitrogen in this ion is plus five. Nitride has a -3 charge and nitrite has a -3 valency.

Answer: ferrous and ferric

Ferric oxide is the chemical name for rust. Ferrous sulfate is the dietary supplement given to pregnant women. The valency for ferric is +3 and +2 is the valency for the ferrous ion.

According to Answers.com, the positive copper ions interact with negatively charged hair. Many copper compounds are blue or green. The minerals malachite and azurite are a brilliant green and a deep sky blue respectively. Other blue minerals containing copper are chrysocola and turquoise. An interesting test to discern the difference between these two minerals in to place your tongue on the mineral. Chrysocola will create a grabbing sensation and turquoise won't. I learned this years ago in the mining business and checked it out.
