A
Tetravalent compounds
GROUP IVB: TITANIUM SUBGROUP
11
Q
- Valence(+3, +5)
- Capable of forming both ionic and covalent bonds
- Readily form pentahalides
- Readily form _______ which are high colored – used as pigments/dyes
A
sulfides
GROUP VA: NITROGEN FAMILY
12
Q
- Oxidation states +2 to +5
- They are unreactive or inert, hence used for corrosion-resistant application in medicine
- Ex. Screens, plates and wires to be left in the body
A
GROUP VB: VANADIUM SUBGROUP
13
Q
- Among the most electronegative elements of the periodic table
- Elements are nonmetallic
- Can form binary compounds with other members of the family
- Form hydrides (RH2)
- With 6 valence electrons
A
GROUP VIA: OXYGEN/SULFUR FAMILY
14
Q
- Have a tendency to unite with oxygen and in such form replace the H of acids to form salts
- Low oxidation state oxides are very basic while the higher ones are acidic (chromates, molybdates, tungstates)
