Ion Names and Symbols
ions
Ion = an atom with a net electric charge due to the loss or gain electron(s). cation = positively charged atom anion = negatively charged atom ion charge = number of protons - number of electrons
magnesium ion
Na
Mg
+1
+2
+1
potassium ion
sodium ion
Directions
Look at the front of each card, then flip to see the back. Look for a pattern in how to write the name and symbol for cations. Also, what types of elements tend to make cations: metals, nonmetals, or metalloids?
Sr
Ca
+2
calcium ion
strontium ion
+2
Al
+3
aluminium ion
+1
hydrogen ion
vARIABLE CHARGE CATIONS
tRANSITION, pOST TRANSTITION, LANTHANOIDS, ACTINOIDS
Ti
These cations have more than one charge option. Example: ~ in rust, iron has a +3 charge ~ in the mineral wustite, iron has a +2 charge Look for a pattern between the name and charge. Hint: the name DOES tell what the cation charge is.
titanium (iV) ion
Hg
Ti
+1
+4
