To answer this question and all other questions about valence electron, you should know where the element is on the periodic table. You can see that F is the 7th group. F is fluorine, which has 7 valence electrons. Fluoride is F with a negative charge which means it has one more electron, so Fluoride has 8 valence electrons.

What is beryllium number of valence electrons?
The beryllium atom has 4 electrons and the valence is 2.
What is the difference of number of valence electrons and periodic table group number?
Valence electrons and group number for metal are same. For non-metals, valence electrons are equal to group number-10.
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
How many number of valence electrons does krypton have?
Krypton has 8 valence electrons.
How many valence electrons in methyl fluoride?
Methyl fluoride, CH3F, has a total of 14 valence electrons. Carbon contributes 4 valence electrons, each hydrogen contributes 1 valence electron, and fluorine contributes 7 valence electrons.
How many valence electrons are present in a fluoride ion?
Fluorine has 7 valence electrons, however, Fluoride (F-) is an anion with a negative charge, giving it one more electron, bumping the number of valence electrons to 8.
What is the valence of Fluoride?
The element Fluorine has a valence number of minus one.And the valence of the fluoride ion (F-) is also minus one.
How do you find number of valence electrons?
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
What is the number of valence electrons for He?
Two valence electrons.
How can you find the number of valence electrons?
the number of valence electrons is the number group on the table its on
How do you find the number of non-valence electrons?
To find the number of non-valence electrons in an atom, you first need to determine the total number of electrons in the atom by looking at its atomic number on the periodic table. Next, subtract the number of valence electrons, which are the electrons in the outermost energy level of the atom, from the total number of electrons. The remaining electrons, which are not in the outermost energy level, are the non-valence electrons.
Which number tells you the number of valence electrons?
The group number in the periodic table tells you the number of valence electrons for main group elements. The group number is the same as the number of valence electrons, except for transition metals.
Number of valence electrons in Ga?
3 electrons !
What is chlorine valence electrons number?

What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
Number of valence electrons in an atom of sulfur?
6 valence electrons
