What is ionic bonding?Ionic Compounds: Attraction among oppositely charged ions.
What is covalent bonding?Ionic Compounds: Sharing of electron density between atoms.
What is metallic bonding?Ionic Compounds: Bonding with delocalized electrons in a metal structure.
What does a Roman numeral in an ionic name specify?Ionic Compounds: The cation charge.
How are monatomic anions often named?Ionic Compounds: With an -ide ending.
Do simple ionic names use molecular count prefixes?Ionic Compounds: Usually no.
What stays intact when naming a polyatomic anion?Ionic Compounds: Its established ion name.
What is NaCl called?Molecular Compounds: Sodium chloride.
What does iron(III) mean?Molecular Compounds: Iron ion charge +3 in the named compound.
What does di- mean in common molecular naming?Molecular Compounds: Two.
What is a polyatomic ion?Molecular Compounds: A charged group of bonded atoms.
What does di- mean?Molecular Compounds: Two atoms of that element.
When is mono- usually omitted?Molecular Compounds: For the first element in a binary molecular name.
What ending is used for the second element?Molecular Compounds: -ide.
Do binary molecular prefix rules name every substance?Molecular Compounds: No; many substances follow other conventions.
What is a subscript?Writing Formulas: A count inside one chemical formula.
What is a coefficient?Writing Formulas: A multiplier of an entire formula in an equation.
What does Ca(OH)₂ contain?Writing Formulas: One Ca, two O, and two H.
What does an absent subscript mean?Writing Formulas: One atom of that element in the formula unit.
What does a subscript describe?Writing Formulas: The count or ratio within one formula unit.
What does a coefficient describe?Writing Formulas: The number of whole formula units.
Why reduce ionic subscripts?Writing Formulas: To express the lowest neutral whole-number ratio.
Can subscripts be changed to balance a reaction?Writing Formulas: No; doing so changes the substance.
