What is the number of valence electrons in an element of group 1 and group 18 respectively?

In the family of alkali metals,the number of valence electrons is _____.

Azimuthal quantum number for valence electron of Na atom is________.

In the modern periodic table, the elements are arranged in the increasing order of their atomic number. This arrangement is based on the modern periodic law, which states that the properties of elements are a periodic function of their atomic numbers. In the modern periodic table, each column is called a group and each row is called a period. Elements within the same group show similarity and gradation in properties. This is due to the same number of electroms in the outermost shell . Based on the above paragraph, answer the following question: What is the number of valence electrons in an element of group 1 and group 18 respectively?
