Write down the electronic configuration of the following elements from the given atomic numbers. Answer the following question with explanation.
e. 11Na,15P,17Cl, 14Si, 12Mg Which of these has largest atoms?
11Na,15P,17Cl, 14Si, 12Mg
element an thier electronic configurations:
The element which has the largest atom is 11Na because atomic size decreases moving across a period from left to the right.
