What is the most stable oxidation state of silicon?
Answer. For the element carbon, silicon and germanium , the +4 state is the most stable.At tin,the +4 state is more stable than +2 but tin (ll)compoundare quite common.At lead , the +2 oxidation state is more stable , through +4 compound do exist.
What is the oxidation state of silicon in sio32 −?
Silicon and oxygen atoms are present. Oxygen is more electronegative than silicon, so each oxygen atom receives its preferred negative oxidation state of -2. The oxidation states of this anion must sum to the net charge of -2. Therefore, the silicon atom receives a positive oxidation state of +4.
