Which sets of elements are in a period?
A period in the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor.
Are niobium and cobalt in the same period?
Niobium and Cobalt are in the same period. Cobalt and Scandium are in the same period.
Does niobium have a charge?
Those found in nature have the +5 oxidation state, but compounds of lower oxidation states (+2 to +4) have been prepared. Quadruply charged niobium, for example, in the form of the carbide, NbC, is used for making cemented carbides….niobium.
