Question

The substances NaF and CaO are isoelectronic (have the 
same number of valence electrons). (a) What are the charges 
on each of the cations in each compound?

Accepted Answer

Hello. Everyone in this video. When you go ahead and determine the charges of the captains and the following isil electronic substances. So we have our M. G. S. And K. C. L. So, some things to notice is that while compounds usually will list are Canadians first, in that case it's going to be our MG. And our cake. So MG and K. Our medals, Our M. G. is in group 2 8 and that's an alkaline earth metal. Then we have our cape, That's going to be in group 18. That's an Alkali metal. And by this trend and groups to a let's go and also write that because this is going to be important. So the skin grip to A. And the case in group one date. So the periodic trends says that our MG. We'll have a charge of plus two And the K. Will have a charge of plus one. So, anything in group 28 will have a plus two charge. Anything in Group one A. Will have a plus one charge. And because of that periodic trend, this is going to be actually our final answer for this problem. All right. Thank you all so much for watching
