Why does fluorine have 7 valence electrons?
The fluorine atom has 7 electrons in the outermost shell and its valency could be 7. But it is easier for fluorine to gain one electron instead of losing seven electrons. Hence, its valency is determined by subtracting seven electrons from the octet and this gives you a valency of one for fluorine.
Does fluorine have 5 valence electrons?
It is the most electronegative element, given that it is the top element in the Halogen Group, and therefore is very reactive. It is a nonmetal, and is one of the few elements that can form diatomic molecules (F2). It has 5 valence electrons in the 2p level
Does fluorine have 9 valence electrons?
The total number of electrons in a valence shell is called a valence electron. The electron configuration of fluorine shows that the last shell of fluorine has seven( 2s2 2p5) electrons. Therefore, the valence electrons of fluorine are seven
Does fluorine have 7 valence electrons?
For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge.
Does fluorine have 7 electrons?
Fluorine has seven electrons of it’s own.
What electron configuration has 7 valence electrons?
7

How many valence electrons has fluorine?
seven valence electrons
What period has 5 valence electrons?
Therefore, the element in the fourth period of the periodic table which has five valence electrons is Arsenic.
Why does fluorine have 7 electrons?
The first energy level has 2 electrons located in the 1s-orbital and the second energy level, which in fluorine’s case is the outermost energy level, has 7 electrons, 2 in the 2s-orbital and 5 in the 2p-orbitals. This means that fluorine has a total of 7 valence electrons.
Does fluorine have 9 electrons?
Fluorine is the ninth element with a total of 9 electrons. In writing the electron configuration for fluorine the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for F go in the 2s orbital.

Does fluorine have 9 or 10 electrons?
Fluorine is the 9th element of the periodic table so its atomic number is 9. The atomic number of an element is equal to the number of protons and electrons in that element. Therefore, a fluorine atom has nine protons and nine electrons
What element contains 7 valence electrons?
The family of elements having seven electrons in the valence shell is halogens, i.e., chlorine, fluorine, bromine, iodine, astatine
How many valence does fluorine have?
The fluorine atom has 7 electrons in the outermost shell and its valency could be 7. But it is easier for fluorine to gain one electron instead of losing seven electrons. Hence, its valency is determined by subtracting seven electrons from the octet and this gives you a valency of one for fluorine.
Do halogens have 7 valence electrons?
7
What is the element with 7 electrons?
For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge.
Does fluorine have 7 outer electrons?
Nitrogen
How many electrons do fluorine have?
9 electrons
What type of element has 7 valence electrons?
halogens
What is the correct electron configuration for an atom with 7 electrons?
Nitrogen is the seventh element with a total of 7 electrons. In writing the electron configuration for nitrogen the first two electrons will go in the 1s orbital.Since 1s can only hold two electrons the next 2 electrons for N goes in the 2s orbital.The remaining three electrons will go in the 2p orbital
Which element has 7 valence electrons in the ground state?
Fluorine has 7 Valence electrons. Valence electrons are those electrons which are present in the outermost shell of an atom. Fluorine has atomic number 9.
What is the charge of 7 valence electrons?
The halogens (Cl, F, Br) all have 7 valence electrons and will gain one electron. This means they have a -1 charge.
