calculate the ground state energy of the O^6+ helium-like ion.  Whats the answer in eV to an appropriate number of significant figures.

Well do you have a formula or something?

Sorry it says explain why the O^6+ ion can be considered to be a helium-like ion, and state what subatomic particles it is composed of and how many there are of each.

then the next question was the one i posted before.

Ever heard of this one?
E=-(k/n²)   
n = principle quantum number k = 1.312 x 10³ kJmol^-1

For someone who posted urgent in capital letters you don't seem very urgent to me. [:)]
