a) iron
b) neon
c) oxygen
d) sodium

There are six alkaline earth metals. They are found in column 2 in the Periodic Table. They have the following properties: they are very reactive, are not found freely in nature. high boiling and melting points, low density, two electrons in the outer shell..The are most likely to be combined (to react) with the oxygen. Reacting with the oxygen the alkaline metals form oxides such as strontium oxide (SrO)
