Which of the following are physical properties of non-metals? select all that apply.
poor conductors
low melting points
brittle
high electronegativities
good oxidizing agents

Answer;

Explanation;

-Non-metals are elements that tend to gain electrons to form anions during chemical reactions. These are electronegative elements with high ionization energies.

-Physical Properties of nonmetals includes; Poor conductors of heat and electricity, dull, brittle solids, most are gases at room temperature, low density, low melting point, not malleable, and also they are not ductile.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
