Question

group 17 elements on the periodic table are mostly

metalloids
metals
nonmetals
solids

Explanation:

Group 17 elements (F, Cl, Br, I, At, Ts) are non - metals. Non - metals have properties such as poor electrical conductivity, high ionization energies, and tend to gain electrons in chemical reactions. For example, fluorine (\(F_2\)) is a highly reactive non - metal gas, chlorine (\(Cl_2\)) is a gas at room temperature (non - metal), bromine (\(Br_2\)) is a liquid non - metal, and iodine (\(I_2\)) is a solid non - metal. Metalloids have properties intermediate between metals and non - metals (e.g., B, Si, Ge etc., not in group 17). Metals (e.g., Na, Mg etc.) have good electrical conductivity and tend to lose electrons. Solids is too general a category as some group 17 elements (F, Cl) are not solids at room temperature.

Answer:

Nonmetals
