Rhenium is similar to technetium.
Technetium is 1 down 4 left of Nickel, Both are transition metals, both are silver and shiny, I don't know exactly what kind of answer you want
Chemists were able to predict the chemical properties of technetium by studying the periodic table and observing trends in the elements around it. Technetium is located in the transition metals group, so it was predicted to have similar properties to other elements in that group with its 7 valence electrons. Additionally, its position in the periodic table suggested that it would exhibit variable oxidation states.
Technetium is one of the rarest elements on the planet. Therefore no one knows if someone is allergic to it and what could cause it.
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.
I would expect all elements in group 1 to have similar chemical behavior to that of sodium, except for hydrogen. Hydrogen is not a metal, but has only 1 valence electron like the other elements in group 1.
You would expect to find them in both.
Technetium is a man made chemical element.
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.
I suppose that technetium cannot be bonded with lithium.
Calcium is in group 2/IIA, so the other elements in that group would be expected to behave most like calcium.
Two elements that would have similar properties are calcium (Ca) and magnesium (Mg). Both elements are alkaline earth metals, have similar reactivity, and form similar compounds. Additionally, they have similar atomic structures with two electrons in their outer shell.
