The elements in Group II also make positive ions, but instead of losing a single electron, their atoms lose 2 electrons when they turn into ions: you will find these metals in the second column of your periodic table so they are Group II.
A simple understanding of positive and negative ions will help you to predict the chemical formulae of most acids, bases and salts. Some atoms e.g. Sodium atoms, Potassium atoms, Fluorine atoms can easily turn into ions by losing or gaining electrons. The most reactive elements do this very readily.
