Elements in the same group as cesium
chicken and duck
Iron and platinum respectively.
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.
The properties of sodium are a result of its configuration of valence shell electrons, so for similar properties, you would look for elements with a similar configuration. Since sodium has one electron in its valence shell (which is one more electron than the previous noble gas, neon), you would look for other elements that also have one more electron than the previous noble gas. The elements in the far left column of the periodic table fit this description. This column includes the elements potassium and lithium.
The newest officially discovered elements are Ununquadiumand Ununhexium so, we'll focus on those.Ununquadium will be part of the Carbon series, so we would expect it to have properties similar to those elements (e.g. 4 electrons in the outer shell). The closest relation to it in that group would be Lead.Ununhexium will be part of the Oxygen series, so, again, we would expect it to have properties similar to those elements (e.g. 6 electrons in the outer shell). The closest relation to it in that group would be Polonium, which is also the first radioactive element.
Elements in the same group (column) have the same properties. All the elements in group one have similar properties. All the elements in group two have similar properties. And so on...
chicken and duck
Elements in the same group or column on the periodic table have similar chemical properties. Helium is in group 18 or the Nobel gases. Elements with similar chemical properties would be the rest of the elements below Helium Neon, Argon, Krypton, Xenon, and Radon
Rb
Iron and platinum respectively.
Elements in a same group have same number of valence electrons and hence similar physical and chemical properties.

Elements in the same group as zinc would be expected to have similar properties.
Uranium and neodymium are very different chemical elements.
Uranium and neodymium are very different chemical elements.
Groups. For example, the halogens share properties, the noble gases share properties.
