Question | Answer |
Alkali metals are in what column | C1, very reactive |
alkaline earth metals | C2, kinda reactive |
Transition metals | C3-13 |
Halogens | C17, not really reactive |
Noble gases | C18, never reactive; has a full configuration |
compound | when one or more atoms are bonded together |
molecule | a compound with covalent bonds |
formula unit | a compound that has ionic bonds |
ionic bonds | - and + charges attract; transfer of electrons because unhappy elements lose/gain electrons |
what type of metal is needed to make an ionic bond | metal+nonmental |
covalent bonds | has no charge because of same charges; sharing electrons |
what type of metal is needed to make a covalent bond | nonmental+nonmetal |
diatomic molecules | elements that always exist as a molecule |
define chemical formula | notation using symbols and #s to represent the composition of a substance |
ex of chemical formula | H20 |
molecular formula | shows the # and kinds of atoms actually present |
ex of molecular formula | c5=c*c*c*c*c |
empirical formula | gives the simplest between atoms (reduced form molecular formula) |
ex of empirical formula | C10H22>>C5H11 |
coefficeints | used to show the prescence of multiple compounds |
ex of coefficient | 2H2O2 (is not H4O4) |
"magic 7" | H2, N2, O2, F2, Cl2, Br2, I2 are the only elements that have a bond with itself (diatomic) |
ammonium | NH4(+) |
carbonate | Co3(2-) |
chlorate | ClO3(-) |
chromate | CrO4(-2) |
hydrogen carbonate (bi) | HCO3(-) |
hydroxide | OH(-) |
nitrate | NO3(-) |
Permanganate | MnO4(-) |
phosphate | PO4(3-) |
sulfate | SO4(2-) |
silver | Ag1+ |
zinc | Zn2+ |
