Question

Use the periodic table to answer the given question, Identify an element with five electrons in the outer subshell.

Answer 1

According to the periodic table,when the electronic configuration of an element having 5 electrons is in its outermost subshell, then its subshell should be ns2 np5.

This is the electronic configuration of the halogen group.

Thus, the element in the outermost shell can be F(2p5), Cl(3p5), Br(4p5), I(5p5), or At(6p5), or Uus(7p5).
