Content Standards being covered:
*Student understands what the letters and numbers stand for in a compound formula, can use those letter and numbers to determine how many of each type of element there are in a formula.
101. A compound’s formula will describe which elements are present in the compound and how many atoms of each.
102. In a compound, the subscript after an element will describe the number of atoms of that element only
103. If a subscript is placed on the outside of a parentheses that contains more than one element, the subscript will apply to all of the atoms within the parentheses*Student understands why bonding (intramolecular forces) occurs between atoms, what types of bonds form when different elements interact, how the bonds form and properties that arise as a result of the bond forming.
110. Metals and Nonmetals will form ionic compounds when they come together
111. Nonmetals and Nonmetals will form molecular compounds bonded by covalent bonds
116. An ion is a charged atom- it becomes charged by either losing or gaining electrons
117. Metals tend to lose electrons and form cations which are positively charged ions
118. Nonmetals tend to gain electrons and form anions which are negatively charged particles
125. The nomenclature of molecular compounds includes the prefixes mono-1, di-2, tri-3, tetra-4, penta-5, hexa-6, hepta-7, octa-8, nona-9, and deca-10 to signify how many atoms of that element are present in the molecule
126. All molecular compound names end in “ide”
127. Ionic compounds are named according to the ions present in the compound
128. For ionic compounds, the cation is always listed first
129. In ionic compound nomenclature, single anions end with “ide”
130. In ionic compound nomenclature, polyatomic ions have unique names that are used for the compound’s name131. Polyatomic ions are charged particles with more than one atom (poly- many, atomic- atoms) covalently bonded togetherHabits of Mind/Life skills being covered:
