This type of chemical bond occurs when electrons are shared by atoms of at least two different elements on the valence level.

Which family of elements are the most stable?

As you move down a column from top to bottom in the periodic table, one trend that is consistent is that atoms get

If an atom has 8 electrons in the valence electron level, that atom is

In the following chemical equation, which are the reactants? 2H2 + O2 yields 2H2O

6CO2 + 6H2O yields C6H12O6 +6O2 is an example of
