Helium is an unreactive gas and neon is a gas.of extremely low reactivity. What if anything do their atoms have in common?

What property do all elements in the same column of the periodic Table as boron have in common?

What property do all elements in the same column of the periodic Table as fluorine have in common?

A cylinder with a movable piston contains 3 moles of hydrogen at standard temperature and pressure. The walls of the cylinder are made of a heat insulator, and the piston is insulated by having a pile of sand on it. By what factor does the pressure of the gas increase if the gas is compressed to half its original volume?

One mole of an ideal gas at standard temperature and pressure occupies 22.4 L (molar volume). What 'is the ratio of molar volume to the atomic volume of a mole of hydrogen?

What are gas masks used and how do they work?

What is the value of gamma for a gas having 'n' degrees of freedom?

For a noble gas atom is it possible to have covalent radius? Explain.

What is the total momentum of the molecules of a mole of a helium gas in a container at rest kept at temperature of 400 K?

State Henry's law. At the same temperature, hydrogen gas is more soluble in water than helium gas. Which one of them will have higher value of K_H ?
