Question

how many valence electrons do elements in group 1, the alkali metals, have? 2 7 1 6

Explanation:

In chemistry (a subfield of Natural Science), elements in Group 1 (Alkali Metals) have 1 valence electron. This is a fundamental concept in atomic structure and chemical bonding, where the group number (for main - group elements) indicates the number of valence electrons. So the correct option is the one with 1.

Answer:

The option with "1" (the third option among the four, showing the number 1).
