A salt is an ionic compound which needs a positive charge ion and a negative ion charge to form a salt.This means that the pair of element should be a metal and non-metal.This is simply because metal atoms tend to lose negative charge electrons and form positive ions while non-metals tend to receive the electrons from the metal atom to form negative charge ions.So answer is Cl and Li.
<em>Answer:</em>
<em>modulate abiotic forces that, in turn, affect resource use by other organisms. both negative and positive effects on species richness and abundances at small scales, but things that a tree does than directly use the tree for ... changes in biotic or abiotic materials. in comparison to some of the other examples we discuss.</em>
