Carbon in group 14
Nitrogen and phosphorus in group 15
Oxygen, sulfur, and selenium in group 16
The halogens (group 17)
The noble gases (group 18)
Nonmetals are primarily found in Groups 14 to 18 of the periodic table. The specific groups containing nonmetals include Group 14 (carbon group), Group 15 (pnictogens), Group 16 (chalcogens), Group 17 (halogens), and Group 18 (noble gases). Notable nonmetals in these groups include carbon (C), nitrogen (N), oxygen (O), fluorine (F), and neon (Ne).
The halogens are the most reactive nonmetals. They belong to Group 17 on the periodic table.
Group 5 nonmetals have a charge of -3. Examples of group 5 nonmetals include nitrogen (N) and phosphorus (P), which commonly form ions with a -3 charge by gaining 3 electrons.
group 17 or halogens
The three classes of group A elements are metals, nonmetals, and metalloids. Metals are typically shiny, malleable, and good conductors of electricity. Nonmetals are usually dull, brittle, and poor conductors of electricity. Metalloids have properties of both metals and nonmetals.
Non metals are listed on right side in periodic table. They belong to group numbers 15,16, and 17

The most active group of nonmetals are those in Group 17, and these are the halogens. The list is headed by fluorine, which is the most reactive element of the group and of the Periodic Table as a whole.
Most nonmetals typically have negative oxidation numbers when in compounds, such as -1 for halogens (F, Cl, Br, I) and -2 for oxygen (O). However, some nonmetals like nitrogen (N) can have positive oxidation numbers depending on the compound.
