hey guys. I have some questions that I'm struggling with. Thanks in advance

1. What are the valence electrons of the sulfur atom in the sulfate ion?

2. What is the electron configuation of the outermost electrons of elements in group IVB?

3. Which group is this from:
1s2 2s2 2p6 3s2 3p6 4s2 3d10 496 4d5 5s2

Merci beaucoup!

1. 6 e- if u draw SO4 u will c it. Also sulfur is in group 6 A

2. Im not to sure about this one since that group has a cut off at Barium (56) but for Ti and Zr is... s2 d2 of whatever shell # those r suppost to be.

3. As for the last one it should be:
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d5 (NOT ...496 4d5 5s2) for a total of 43 electrons (technetium) group VIIB
