The two properties of most non metals are high ionization energy and poor electrical conductivity. The correct option among all the options that are given in the question is option "1".
In general it is known that nonmetals are very poor
conductors of heat and electricity. The nonmetals that are solid are normally
very brittle and has very little or no metallic luster at all. Nonmetals are
highly reactive and show variety of chemical properties. It can also be pointed
out that the nonmetals gain electrons very easily.
Answer:
Initially 
of nitrogen dioxide were in the container .
Explanation:
Volume of the container at low pressure and at room temperature =
Number of moles in the container = 
After more addition of nitrogen gas at the same pressure and temperature.
Volume of the container after addition = 
Number of moles in the container after addition=
Applying Avogadro's law:
(at constant pressure and temperature)
Initially of nitrogen dioxide were in the container .
Answer: has properties similar to other elements in group 18, does not react readily with other elements, is part of the noble gas group
Explanation: I’ve done on edg before
Answer:
8510 mol
Explanation:you must divide both of the molar masses into each other
If you mean the number of Significant Figures/Digits in 23.45, it would be 4. This is because every single non-zero digit is counted as a significant figure
