Lithium and potassium have similar chemical properties because they both have the same number of valence electrons.
A valence electron is an electron that is part of an atom's outer shell and can take part in the synthesis of a chemical bond if the outer shell is open. Each atom in the bond contributes one valence electron to create a shared pair in a single covalent bond.
The chemical properties of an element, such as its valence—whether it can connect with other elements and, if so, how quickly and with how many—may be affected by the existence of valence electrons. In this approach, the electrical arrangement of an element greatly influences its reactivity. A valence electron can only be found in the outermost electron shell of a main-group element, but it can also be found in an inner electron shell of a transition metal.
