Which elements would you expect to be similar to technetium and why?
You would expect manganese and rhenium to be similar to technetium, because they are in the same column of the periodic table.
molybdeum(Mo) or ruthenium (Ru) Actually, elements with similar chemical properties as Technetium would be Mn, Re, and Bh. This is because elements in the same group/family (column) have similar chemical properties. Elements in the same period (row) have the same number of energy levels (or shells).
Where on the periodic table would you expect to find elements with similar properties and chemical characteristics?
The newest officially discovered elements are Ununquadium and 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…
