Nonmetals tend to form what ions?

Answer 1

Negative ions with a charge equal to the number of electrons required to complete their octet of valence electrons.

Elements with four or more valence electrons and a high electron affinity—the amount of energy released when an atom gains an electron—are typically classified as non-metals.

The high electron affinity lasts until the valence shell is full, so reactions involving these atoms tend to occur in ways that allow them to pick up one or more electrons. Thus, elements in column 17 (halogens) form ions of charge -1, elements in column 16 form -2 ions, and elements in column 15 that are non-metals (though not all of them are!) form -3 ions.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
