Answer is: halogens ans noble gases.

The nonmetals are divided into two categories: reactive nonmetals and noble gases.

Halogen elements are in group 17: fluorine (F), chlorine (Cl), bromine (Br) and iodine (I). They are very reactive and easily form many compounds.

Noble gases are in group 18: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). They have very low chemical reactivity.

A sample of O2, under occupies 500ml at 25.0°C. What volume will the sample occupy at 0.0°C
NeX [460]

Answer:

458ml

Explanation:

According to charles law, $\frac{V_{1}}{T_{1}} =\frac{V_{2}}{T_{2}} $

Given values,

Volume occupied $V_{2}=500ml$

Temperature $T_{1}=25.0^{\circ}C=25+273=298K$

Second temperature $T_{2}=0.0^{\circ}C=273K$

Volume $V_{2}=?$

From charles law, $V_{2}=\frac{V_{1} \times T_{2}}{T_{1}}$ \\$=\frac{500 \times 273}{298}$\\$=458ml$

$\therefore$ Volume occupied by the oxygen at 0.0°C is 458ml
