Which of the following groups does not contain transition elements?
Group 1
Group 13
The modern periodic table has 18 vertical columns called groups and 7 horizontal rows which are called periods. Every group contains a bunch of elements with similar chemical properties and periods contain elements with the same number of shells.
The elements from group 3 to group 12 in the periodic table contain all the transition metals.
Since we are asked which groups do not contain transition elements. Therefore group 13 and group 1 do not contain any transition elements.
