[xe] 6s2 is the noble gas configuration for which element

We are tasked to find the element which has a noble gas electronic configuration [Xe] 6s2. First tasked is to find the molecular number and add 2 as the last orbital electron. Thus, we have an element that has a molecular number of 54+2= 56. Looking on the periodic table, find an element that has 56 as the molecular number. That element is Barium (Ba).
