- 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.
