What is an ion?
An atom that either gains or loses electrons to become charged (+/-).
CO
carbon monoxide
MgO
Cu2O
KOH
Potassium hydroxide
Where do you find transition metals in the periodic table?
Generally in the middle, rectangular area of the periodic table (Group 3-12).
SCl4
Sulfur tetrachloride
AlBr3
Fe3P2
Iron (II) phosphide
Ca(BrO3)2
Calcium bromate
Generally, elements on the left side of the "staircase" are metals while the ones on the right side are nonmetals.
NH3
nitrogen trihydride
K3P
Potassium phosphide
FeO
Iron (II) oxide
NH4Cl
Why do metals tend to form cations?
Because metals tend to donate electrons, causing the atom to be positively charged.
P4Se3
Tetraphosphorus triselenide
Calcium chloride
CaCl2
HgO2
Mercury (IV) oxide
Cu(ClO4)2
Copper (II) perchlorate
Why do transition metals require Roman numerals when naming them?
Because they don't have a constant charge as it can donate different number of electrons.
XeO4
xenon tetroxide
Gallium oxide
Ga2O3
Fe(CN)2
Iron (II) cyanide
Ni(SO3)2
Nickel (IV) sulfite
