Uranium and neodymium are very different chemical elements.
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...
because,he predicted some possible chemical formulas of the then undiscovered elements between the elements in his periodic table. so he concluded that more elements with specific properties would be discovered.
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
Uranium and neodymium are very different chemical elements.
Uranium and neodymium are very different chemical elements.
Elements in a same group have same number of valence electrons and hence similar physical and chemical properties.
same number of valence electrons, so are their chemical properties more or less the same.
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.
You would expect to find them in both.

The "metalloid elements", including at least As and Sb; many chemists would also include Ga, Ge, Te, and possibly Po.
Elements in the same group as cesium
