This number tells you the number of protons an atom has in its nucleus What is the Atomic Number? This number refers to the number of protons and neutrons an atom has in its nucleus What is the Mass Number? Electrons are found in orbitals surrounding the nucleus. How many electrons can fit into the first two energy levels combined? What is ten? Atoms which have the same atomic numbers but different mass numbers are called What are Isotopes? These subatomic particles have a negative charge What are electrons? These subatomic particles have a mass of 1 and a charge of 0. What are neutrons? Virtually all of the mass of an atom is found in its. What is Nucleus? These subatomic particles are found in the nucleus and have a charge of +1 What are protons? An atom is considered to have no net charge because the number of electons is equal to the number of What are protons? Compounds are formed when 2 or more _________ are chemically combined. What are elements This type of chemical bonding results from the sharing of electrons. What is covalent bonding? The type of chemical bonding that occurs due to a transfer of electrons is called What is Ionic Bonding. The ability of an element to form bonds is determined by the number of electrons in its_________ energy level (shell) What is valence? Elements are most stable when they have this many electrons in their valence energy level What is 8? Inorganic molecules are molecules that lack both ____________and ____________. What are carbon and hydrogen? Substances which donate OHion when placed in a water solution are know as What are bases? Substances which donate H+ ions in a water solution are known as What are acids? Acids and bases are important inorganic molecules. What do they both help to maintain within our bodies? What is pH levels. DAILY DOUBLE Water is a very important inorganic molecule. What 3 characteristics of water make it so vital to life? 1.It is the best known solvent 2. It is relatively stable 3. It ionizes An atom, or group of atoms, that have gained or lost one or more electrons is called What is an ion? These inorganic substances help to maintain proper nerve cell function and help to keep our bones strong, among other thngs. What are salts? (or minerals) What would be the products of the following reaction. NaOH + HCl What is NaCl and H20 A group of 2 or more elements occurring together that are not chemically combined is a known as What is a mixture? This scale determines the concentration of H+ ions in a solution What is the pH scale.
