Slivka’s Square Elements
A
3x3 beginning with Si, P, S
25
Slivka's Square Polyatomic Ions rules
1. All of these elements' are accompanied by 4 Os as -ate ions, and 3 Os as -ite ions
2. Their charges are determined by the column their in as oxidation states
3. All other elements outside of the square have 3 Os as -ate ions, and 2 Os as -ite ions
26
Exceptions to Slivka's Square
Nitrate: NO3 Charge: -1
Carbonate: CO3 Charge: -2
27
Charges on the Periodic Table
+1, +2, +3, ..., -3, -2, -1
28
per- prefix
the polyatomic ion has an extra oxygen atom than the -ate ion
29
hypo- prefix
the polyatomic ion has two fewer oxygen atoms than the -ate ion, and one fewer than the -ite ion
