Explanation:
Since, it is given that critical temperature of Argon is 150.9 K and critical pressure of Argon is 48.0 atm.
It is known that gas phase of neon occurs at 50 K. As the boiling point of Ar is more than the boiling point of neon which means that there is strong intermolecular force of attraction between argon molecules as compared to neon molecules.
This is also because argon is larger in size. As a result, induced dipole-induced dipole forces leads to more strength in Ar as compared to Ne.
Scientists can measure the height in
different units but problem could arise when they compare all the measurements.
That is the reason there is standard units for measurements.
<span>There may be error arises when an
American scientist is measuring the height of an object in inches and other Australian
scientist is measuring the height of same object in meters. Their data cannot
be compared because they are using different units to measure height.</span>
Metalloid
Explanation:
If an element is lustrous, brittle and a semi-conductor, it is best classified as a metalloid.
Metalloids shares attributes of metals and non-metals.
- They are often described as semi-metals as they do not share the full properties that makes a metal a metal.
- Metalloids are lustrous but not malleable like metals.
- They do not conduct electricity but they do so on certain conditions.
- Examples are silicon, germanium, boron, arsenic e.t.c
- They are usually found in the middle of the periodic table.
- They are not readily alloyed with metals.
