Question

The relationship between the number of valency electrons and the valency for the elements sodium and aluminum

Answer 1

Answer:Atomic number of Sodium (Na)is 11 and valency 1

Atomic number of Aluminium (Al) is 13 and valency 3

Explanation:no of valence electrons in sodium is 1 so valency also 1 and in aluminium valence electrons are 3 also valency 3 . So the number of valence electrons is directly proportional to valency. (Note:sign not included)
