Answer:
Cd2+ : 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 4d10 or [Kr] 4d¹⁰
Explanation:
Before proceeding to write out the electron configuration of Cd2+, we have to obtain the electron configuration of Cadmium (Cd),
Cadmium has an atomic number of 48, this means that a neutral cadmium atom will have a total of 48 electrons surrounding its nucleus.
The electronic configuration of Cadmium is;
Cd: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10
The shorthand notation is given as;
Cd: [Kr] 4d¹⁰5s²
Cd2+ means that it has two less electrons, hence it's electron configuration is given as;
Cd2+ : 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 4d10 or [Kr] 4d¹⁰

<span>The alkali metals and hydrogen are reactive because they have only one electron to give in order to complete their valence shell. It is easier to give that one electron so when given the opportunity they will. This means they will react with anything polar or willing to take an electron.</span>
<span>Basically, temperature changes the reaction, which means that it would be a chemical change since it changes the formation of bonds and reactions. </span>
Answer:
The detailed calculation is shown in the attached file.
last condition (1000 K in 150.000 dm3) will have the least deviations and it is the condition where real gas will behave as ideal gases
Explanation:
Real gas behave more ideally or they tend towards ideality when there is the least deviation, or their inter-molecular forces between their molecules are mainly responsible for their deviations as such gases with the strongest intermolecular forces shows the strongest deviations. As such, when their is an increase in temperature and volume and a decrease in pressure, real gas tends towards ideal gas in this case.
From the three conditions given, it is obvious that the last condition(1000 K in 150.000 dm3) will have the least deviations.
