A substance that cannot be broken down or decomposed into two or more different substances is called a(n) element Acids, bases, and salts belong to a large group of compounds called electrolytes The water molecule has two distinct ends, each with a partial electrical charge. Because of this structure, water is said to be polar Acids release hydrogen ions. The atomic number tells you the number of protons in the nucleus. Hydrogen bonds result from unequal charge distribution on a molecule. Such molecules are said to be polar An atom can be described as chemically inert if its outermost electron shell contains _____ electrons. eight Salts - can form as the result of a chemical reaction between acids and bases. - are electrolytes. - will form crystals if the water is removed. Chemical bonds formed by the sharing of electrons are called: covalent Electrolytes are: called cations if they have a positive charge. Hydrolysis _____ a water molecule. breaks down compounds by adding The total number of electrons in a neutral atom equals the number of: protons in its nucleus.

Ionic bonds are chemical bonds formed by the: transfer of electrons from one atom to another. The element oxygen has an atomic number of 8, which means it contains: eight protons. A weak acid: dissociates very little in solution. Which of the following is not a subatomic particle? Radon Atoms with fewer than eight electrons in the outer energy level will attempt to lose, gain, or share electrons with other atoms to achieve stability. This tendency is called the octet rule.
