Element x has five valence electrons element why has one valance electron an element z has one valance electron which two of these elements are most likely to have similar properties explain your answer

Element Y and Z

Explanation:

The valence is related to the number of electrons needed or that are too much to have the last level of the complete atom. In the case of valence 1 (elements y, z) corresponds to group I (alkali metals such as sodium, potassium, lithium). Taking into account Valencia 5, corresponds to group 15 (Nitrogen, Phosphorus, among others), where they require 3 electrons to complete their octet.
