Question

Below each substance in the first column write the letters from the other two columns to match. One is done for you.

Substance	Property $1$	Property $2$
$1 .$ Neon	$A .$ Metal	$p .$ Ductile
$B, s$	$B .$ Nonmetal	$q .$ Malleable
$2 .$ Graphite	$C .$ Solid	$r .$ Kills germs
	$D .$ Liquid	$s .$ Nonreactive gas
$3 .$ Iodine		$t .$ Cuts glass
		$u .$ Conducts electricity
$4 .$ Aluminium

$5 .$ Diamond

$6 .$ Mercury

Accepted Answer

Neon is a non-metal, it is an inert gas and is non-reactive because it has complete octet configuration.

Graphite is a solid non-metal, but it conducts electricity, it is an exception from the properties of non-metals.

Iodine is a solid non-metal; is used as an antiseptic to kill germs as it is non-reactive also to some extent.

Aluminium is a solid metal which is malleable and ductile, due to this property it is used for making aluminium foils and as it is a good conductor of electricity, it is used to make aluminium wires.

Diamond is a solid non-metal and is the hardest material known; it is used to cut glass.

Mercury is the liquid metal; most of the metals exist as solids; mercury is an exception. It is used in thermometers. Like all metals, it is ductile, malleable and conducts electricity.
