<h3><u>Answer and explanation;</u></h3>
Ideal gas law is the mathematical relationship among pressure, volume, temperature, and the number of moles of a gas.
The ideal gas law is given by;
PV=nRT, where
P is the Pressure
V is the volume of the gas.
n is the number of moles
R is the gas constant and
T is the temperature
Able to be hammered or pressed permanently out of shape without breaking or cracking. An example would be hot metal being shaped.
Elements in the same column of the periodic table exhibit similar properties (periodicity). Carbon, in Group XIV (14), and elements below it in the same column react in similar fashion. The most similar element to carbon is silicon (Si).
It would be Xe because all of the other ones aren't filled up in the correct order which only happens during an excited state.
