an atom of carbon has 4 electrons in its outermost shell so ionic charge is 4+ or 4-

  • cwrw238
Si is in same group as carbon so its also 4+ or 4- - i think these elements are all in same group ( group IV)

yup - all have same ionic charge

but isn't pb is 2+?

oh - well my chemistry is a bit rusty - long time ago - i'm sure about C, SI and Ge being 4 though ill check it out

ok ionic charge of lead is 2+ or 4+ - of course its not negative
cwrw238
  • cwrw238
Sn is also 2+ or 4+ Pb is usually +2 whereas Sn is usually 4+

germanium 4+

can one atom has 2 charge?
cwrw238
  • cwrw238
C and Si both 4+ or 4-
cwrw238
  • cwrw238
it depends on the compound it is in e.g. you can have SnCl2 and SnCl4
cwrw238
  • cwrw238
Sn has charge 2+ in first compound and 4+ in the second
cwrw238
  • cwrw238
carbon compounds with charges are very rare - carbon usually forms covalent bonds where electrons are shared

ok?

The ionic charge of the element in question depends on it's oxidation state in the molecule it is part of. Since these elements are generally nonmetallic, they mostly form covalent bonds rather than ionic ones. However, if they do form ionic bonds the charges can vary from 2+ to 4+. Sn has 2 oxidation states, 2+ and 4+ depending on the molecule and Pb usually exists as 2+ The latter 2 act more as metals than nonmetals

The solution is that they are all group 4 elements and are not completely metals or Non-metals. Hence they form Covalent bonds and hence they dont have ionic charges. but as the group decreases, ionic nature increase. so Pb and Sn have +2 and +4 states...
