Atoms bond in certain proportions to form (1)______. They do so to achieve greater stability by acquiring a (2)______configuration of valence electrons. If the two atoms are a metal and a nonmetal, the metal will (3)______electrons to the nonmetal. Because the resulting particles will then have a different numbers of positively-charged protons and negatively charged electrons they will be electrically charged. Such charged particles are called (4)______. Oppositely charged particles combine, forming (5)______bonds, so that the overall charge of the (6)______compound is zero.

It is possible to predict the proportions of atoms that will form a stable ionic compound. For instance, knowing the magnesium (in Group 2) tends to form +2 ions and oxygen (in Group 16) tends to form -2 ions, we can conclude they will join in a 1 to 1 ratio, and thus will have the formula MgO. (The positive ion is always listed (7)______in a chemical formula.)

If the particles lack a stable noble gas configuration of valence electrons and they are both nonmetals, neither will give up electrons. Instead they can achieve greater stability by (8)______electrons, forming (9)______bonds. The resulting particle is called a (10)______or covalent compound. Ions are not formed and are not involved.

Due to the nature of the different types of bonds, ionic and covalent compounds have distinctive properties. (11)______compounds conduct electricity when melted or dissolved; (12)______compounds don't. (13)______compounds, like oil, are often not soluble in water (but some, like sugar, are soluble). (14)______compounds are generally highly soluble in water.

When a chemical reaction takes place, the products of the reaction usually have very different properties than the reactants have. If a solid product forms in a solution (often making the solution look cloudy), we call that solid a (15)______.

Completion

The elements in the periodic table are arranged in vertical columns called (16)______. Metals are on the (17)______and lower sides of the periodic table. Nonmetals are on the right and (18)______sides.

Every substance is either an element or a (19)______. A compound is either (20)______or ionic in nature. Molecular compounds are composed of two or more (21)______. The representative particle of a molecular compound is a (22)______. Ionic compounds are composed of oppositely charged (23)______combined in electrically neutral groupings. The charges of the ions of most elements in groups 1, 2, and 13-17 can be determined by the position of these elements in the periodic table.
