The force that holds two atoms together is called a(n) (1)__________. Such an attachment may form by the attraction of the positively charged (2)_________ of one atom for the negatively charged (3)________ of another atom, or by the attraction of charged atoms, which are called (4)_______. The attractions may also involve (5)_______ electrons, which are the electrons in the outermost (6)_________. The (7)_________ are a family of elements that have very little tendency to react. Most of these elements have a set of eight outermost electrons, which is called a stable (8)________. The relatively stable electron structures developed by loss of electrons in certain elements of groups 3, 4, 13, and 14 are called (9)______.
