Plz help
I don't know chem that well

To find these answers you can just pull up the picture of the periodic table. The # of protons can be found at the top of the element, AKA, the atomic number. The group number is which column the element is in, there are 18 groups, counting from left to right. The valence electrons and oxidation are found similarly by which column they are in, each column is different so I would advise looking it up for each element. And lastly, the Ion that will form is found by finding the ionic charge of each element. I hope this helps. :)

What’s the solution?

Ithink the answer is b.
