Which of the following has the fewest valence electrons?
A. nitrogen (N)
B. boron (B)
C. lithium (Li)
D. fluorine (F)
is it C?
I believe its C, I'm not a teacher but just trying to help.
C is correct.
No, the correct answer is D. fluorine (F). Fluorine has the fewest valence electrons among the listed elements.
To determine which of the given elements has the fewest valence electrons, we need to refer to the periodic table. Valence electrons are the electrons in the outermost energy level of an atom.
Looking at the periodic table, we can determine the number of valence electrons in each element:
A. Nitrogen (N) is located in Group 15 of the periodic table, which means it has 5 valence electrons.
B. Boron (B) is located in Group 13 of the periodic table, which means it has 3 valence electrons.
C. Lithium (Li) is located in Group 1 of the periodic table, which means it has 1 valence electron.
D. Fluorine (F) is located in Group 17 of the periodic table, which means it has 7 valence electrons.
As we can see, lithium (Li) has the fewest valence electrons with just 1 valence electron. Therefore, the correct answer is C.
