For a main-group element, what is the simplest way to determine how many valence electrons it has using the periodic table?
A
Use the element’s group (column) number: the group number equals the number of valence electrons for main-group elements (e.g., Group 17 has 7).
B
Count the total number of electrons in the atom: the total number of electrons always equals the number of valence electrons.
C
Use the element’s atomic number: the atomic number equals the number of valence electrons.
D
Use the element’s period (row) number: the period number equals the number of valence electrons.
