Question

The Periodic Table Question 3 of 10 Based on the trend in valence electrons across periods for main-group elements, how many valence electrons does fluorine (F) have? O A. 4 B. 7 O C. 6 D. 5 SUBT​

Answer 1

7

Step-by-step explanation:

Answer 2

B. 7

Step-by-step explanation:

Fluorine has 7 valence electrons in its orbitals.

The valence electrons are electrons in the outermost shell of an atom. Every element has a certain amount of valence electrons.

• Fluorine belongs to the 7 - group on the periodic table.
• Every element in this group has 7 electrons in their outermost shell.
• The elements in the group are called halogens.
• Other elements in this group are fluorine, chlorine, bromine, iodine and astatine.
