1000 cm^3 - ANSWER✔✔-1 L
Angstrom (Å) - ANSWER✔✔-1 x 10^10 m
1 amu - ANSWER✔✔-1.66 x 10^-24 g
Properties of metals - ANSWER✔✔-conduct electricity/heat, ductile(can pull into thin wire),
malleable(can pound into thin sheets), bendable, shiny (high luster), like to lose electrons when forming
ions
properties of nonmetals - ANSWER✔✔-many are gases/powders, solids are brittle, poor conductors of
heat and electricity, like to gain electrons when forming ions
properties of metalloids - ANSWER✔✔-properties of both metals and nonmetals: okay conductors, can
be shiny or dull, semiconductor electronics (computer chips) based on these materials
molecular compound - ANSWER✔✔-made of nonmetals
ionic compound - ANSWER✔✔-made from metals and nonmetals or with polyatomic ions
molecular formula - ANSWER✔✔-describes the actual number of atoms in a molecule
empiracal formula - ANSWER✔✔-describe the simplest whole number ratio of atoms in a molecule
Hydroxide - ANSWER✔✔-OH charge -1
Nitrate - ANSWER✔✔-NO_3 charge -1
Nitrite - ANSWER✔✔-NO_2 charge -1
