In which row are the chemical elements in the order of increasing number of valence

In which row are the chemical elements in the order of increasing number of valence elements? 1) Li, Be, B 2) S, P, C 3) K, Na, Li 4) C, Si, Ge

In order of increasing the number of valence electrons, the elements are located in the answer to task number 1: lithium (Li) – beryllium (Be) – boron (B). This is due to the location of the element lithium in the first group of the periodic table of D.I. Mendeleev, beryllium – in the second group and boron in the third.

The fact is that the maximum valence of an element, as a rule, is equal to the number of the group in which it is located. Consequently, lithium has only one valence electron, beryllium already has two, and boron has three.

The rest of the groups of elements, from answers 2), 3) and 4) are not arranged in increasing order of the group number, therefore, these answers are not correct for this task.
