Which of the elements below has no valence electrons?
a) Ar+ b) Ga+ c) Mg+2 d) S-2 e) F-

I don't know what it means by "no" valence electrons. Does that mean it has eight, but since it's filled it essentially means 0? Even though, I end up with Mg+2, S-2, and F- as the ones that have 8 valence electrons. But the question didn't say atoms or ions, it said elements. So would I forget about the charges and choose the "element"? What what be the correct choice?

Hi, got stuck on this for my revision:

A chemical company recieves an order to supply 100 tonnes of strontium. They need to calculate how much ore to process.
The ore typically contains 2% by mass of SrCO3.
Calculate the mass of ore that the company would need in order to produce 100 tonnes of Strontium.

1 tonnes = 10^6 g

Thanks!
