An ideal gas is one in which each atom has no influence on its neighbors. So it would not liquify or solidify, because that would require some attractive force that one would exert on the other. So the real gas that most resembles an ideal gas is the one that is hardest to liquify, and that would be helium, which doesn't liquify at atmospheric pressure until you get it down to 4.2 degrees C from absolute zero (in other words, to 4.2 degrees Kelvin). No other gas has such a low boiling point.
short answer: helium
Explanation: see below
an ideal gas in which each atom has no influence on its neighbors, so it would not liquify or solidify.
so the real gas that most resembles an ideal gas is helium, which doesn't liquify until about 4 degrees celsius from absolute zero. (no other gas has such a low boiling point)
helium atoms also have minimal intermolecular forces/interactions because 1) there are no ionic forces, 2) no hydrogen bonding, and 3) given the small number of electrons on each atom, even london-dispersion forces are quite weak--2nd only to hydrogen (if H was judged solely on its london-dispersion abilities, but H is a special molecule...)
3. He
Helium.
Properties of an ideal gas: 1) volume is negligible as molecules are far apart. 2) all collisions between molecules are perfectly elastic, meaning that all energy is conserved. 3) there are no attractions between the different gas particles 4) ideal gas obeys the law PV=nRT where n is the number of moles. *most gasses conform to ideal gas properties, except at low temperatures and high pressures

The main reason is because measurable properties have a defined limit (feet are defined by their relation to other forms of measurement like 12 inches). Were as observable properties can be observed differently by different people. Most importantly measurable properties are far easier to record and check by replication of a scenario.
The properties from the original elements are all left behind; almost no compound shows any of the properties of its constituent elements (the most widely used example of this is sodium and chlorine forming sodium chloride).

The chemical properties of calcium are most similar to (in between) the chemical properties of magnesium and strontium.
Lanthanides have properties similar to Cerium
Halogens have similar properties. All of them form anion.
A Nitrogen atom shows the most similar properties to an Oxygen atom.
There is no fully objective answer to this question. Many chemists would consider that two lanthanide elements with atomic numbers differing by only one would be likely to qualify. Another possibility is the pair zirconium and hafnium. These are very similar in most chemical characteristics but differ greatly in electron capture tendencies in nuclear reactors.
helium behaves more ideally.... all the conditions for an ideal gas are almost the same in he and hydrogen except hydrogen is diatomic so it has forces of attraction and helium is monoatomic.
The element that would have properties most similar to the new element would be an element that lies in the same group as the new element. Specifically, the element with the most similar properties will lie directly above or below that element in the group.

Silicon, which is just below carbon, and Germanium are the two elements that are most like carbon.
