Non-metal ions typically form negative ions (ie: Cl-) Therefore they now have an extra electron which is protected from the positive pull of the nucleus by the other electrons and therefore the electron shell has now expanded, making nonmetal ions larger than nonmetal atoms

Why non metals found in more compounds than metals?
Even though there are about five times more elements that are metals than nonmetals, there are more nonmetals than metals found in compounds. Nonmetals form many more compounds than metals because living organisms are composed almost entirely of nonmetals. There are more than 8.7 billion living organisms on Earth.
Are there more nonmetals than metals on the periodic table?
Yes. There are only about 20 nonmetals and only 7 metalloids. The rest of the elements are metals.
Are nonmetals more electronegative than metals?
Yes, non-metals are more electronegative than metals. Fluorine is the most electronegative element, and it is a nonmetal.
Which have larger ionic sizes metals or nonmetals?
nonmetals
Are covalent bonds more likely to be found in compounds containing both metals and nonmetals or compounds containing only nonmetals?
Nonmetals and metals

Yes. There are only about 20 nonmetals and only 7 metalloids. The rest of the elements are metals.
What are conductivity metals?
Metals have a higher electrical and thermal conductivity than nonmetals.
Which elements of the periodic table are metals and nonmetals?
metals elements conduct electricity better than nonmetals elements but not as well as metalloid elements
Do nonmetals have lower densities than metals?
No, they have higher density than non-metals comparatively.
What is the most reactive group of a metals and nonmetals?
Metals: alkaline metals Nonmetals: halogens
Do nonmetals have always higher electron affinity than metals?
That is the trend of the periodic table. From left ( where the metals are ) to the right upper corner ( where the most electronegative nonmetals are )
Are nonmetals more electronegative than metals?
Yes, non-metals are more electronegative than metals. Fluorine is the most electronegative element, and it is a nonmetal.
How are metalloids differents from metals and nonmetals?
because metalloids usually have properties that are similar to metals and nonmetals
What kind of bonds do metals and nonmetals form?
Metals and nonmetals form ionic bonds.
Are atoms of nonmetals among the largest atoms?
Atoms of nonmetals tend to be smaller than atoms of metals in the same period.
Would you expect nonmetals to have larger electron affinities than metals?
Yes. Non metals have larger electron affinity than metals as non metals accept electrons more easily than metals.
