How many elements in one period
WebA period on 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. … WebPeriods from the fourth onwards have a space for ten d-block elements. Most or all of these elements are also known as transition metals because they occupy a transitional zone in properties, between the strongly electropositive metals of groups 1 and 2, and the weakly electropositive metals of groups 13 to 16.
