it has 7 valence electrons, which is the number of electrons on the outer energy level, so it needs 7.
A Fluorine atom has an atomic number of 9. Draw out the electron shell diagram for Fluorine. Is a Fluorine atom more likely to gain, lose or share electrons to fill its valence shell?
The number of electrons is always the same as the atomic number. That gives you the number of protons and electrons. The atomic mass has nothing to do with it. What is the atomic number? That is your answer.
In an uncharged atom, the number of electrons is always equal to the atomic number, in this instance, 9.
nine
Fluorine's atomic number is 9. Thus, fluorine has 9 protons and 9 electrons. As with every atom, all 9 of fluorine's electrons are found in the electron cloud.
The total number of electrons in a neutral fluorine atom is 9, which is the atomic number of fluorine.
In a neutral atom of fluorine, there are 9 electrons. The number of neutrons varies with an isotope's mass number.
Fluorine has 9 in total. 7 in the outermost shell
it has 9 electrons atomic number= number of protrons and electrons and atomic mass-atomic number=neutrons
A Fluorine atom has an atomic number of 9. Draw out the electron shell diagram for Fluorine. Is a Fluorine atom more likely to gain, lose or share electrons to fill its valence shell?
fluorine
Fluorine has 9 electrons to match its atomic number.
The number of electrons is always the same as the atomic number. That gives you the number of protons and electrons. The atomic mass has nothing to do with it. What is the atomic number? That is your answer.
Since fluorine and chlorine are in family 7A, they each have 7 valence electrons. The number of the family corresponds to the number of valence electrons.
Fluorine has the atomic number of 9. This means it has 9 protons in the nuclei of its atoms. So, a neutral fluorine atom would also have 9 electrons.
In an uncharged atom, the number of electrons is always equal to the atomic number, in this instance, 9.
The atomic number of an element tells you how many electrons there are and how many protons there are.
