Periodic

Answer 13

Having a regular, repeating pattern

Question 14

Periodic Law

Answer 14

The law that states that the chemical and physical properties of elements are periodic functions of their atomic numbers

Alkali metals

Answer 15

The elements in group 1 of the periodic table, the most reactive metals, have one valence electron
