Which of the following group 1 metals has the strongest metallic bond, Li, Na, K or Rb?RbNaLiK
Question
Which of the following group 1 metals has the strongest metallic bond, Li, Na, K or Rb?RbNaLiK
Solution
The strength of metallic bonds in group 1 elements (alkali metals) decreases as you move down the group. This is because the size of the atoms increases down the group, meaning the outermost electrons are further from the nucleus and therefore less strongly attracted to it. This makes the metallic bonds weaker.
So, in the group 1 metals you mentioned (Li, Na, K, Rb), lithium (Li) would have the strongest metallic bond.
