Metallic element calcium combines with the nonmetallic element oxygen?
Simple. Here is the equation:
Calcium + Oxygen --> Calcium Oxide
Ca + O --> CaO
There is no single description for the combination of two undefined elements: if they are the same element and nonmetallic, it would be a molecule. if they are the same metallic element, they would form a metallic structure. if they are different elements and are both nonmetallic, they could be described as either a compound or a molecule (or both; a molecular compound). if they are both metals, they would form an alloy. if one…
Antimony is a metalloid which means that it has metallic and nonmetallic properties and it is element 51 in the periodic table lying in the diagonal metalloids in the p group. The metallic and nonmetallic properties may be, for example, that it is grey and shiny like a metal but it may also be brittle and not conduct heat and electricity like a nonmetal.
