What happens to non metals across the periodic table?

Answer 1

Moving from left to right across a period, up to but not including the noble gases (group 18), reactivity increases. Moving down a group, the reactivity of the elements decreases. Fluorine is the most reactive element.

Answer 2

Nonmetals tend to increase in electronegativity and gain more nonmetallic properties as you move across the Periodic Table from left to right. They have high ionization energies, high electron affinities, and tend to form covalent bonds with other elements. They are poor conductors of heat and electricity.

Answer 3

The nonmetals in Group 6A will gain two electrons because they have 6 electrons in their valence shell. The nonmetals in Group 7 will gain one electron.

Answer 4

Yes, but they also can gain 2 or 1 (respectively) to form neg. ions (-2, -1)
