Halogens each have 7 valence electrons.
What else can I help you with?
What happens to the valence electron in an alkali metal when it combines with a halogen gas?
This electron is lost.
How many electrons are in the outer electron level of the halogen?
7 electrons are on the outer (valence) shells of all halogens
How many valence electrons do the halogen have?
The number of electrons in the valence shell of a halogen is 7. What is probably the most significant feature of halogens is that they all are one electron short of the number of electrons required to fill their valence shells, eight. That means they will have similar chemical properties, i.e., they all are on the lookout to borrow one electron.
If atoms of a halogen non metal gain one electron the atoms then have how many valence electrons?
This atom become an anion with negative charge -1.
How many valence electrons does an atom of any halogen have?
A halogen is located in group 17 of the periodic table, so the electron configuration for the valance electron would be ns2np5 (n=energy level). So all halogens have 7 valance electrons.
How many valence electrons does the halogen family have?
7
How many valence do the halogens have?
The number of electrons in the valence shell of a halogen is 7. What is probably the most significant feature of halogens is that they all are one electron short of the number of electrons required to fill their valence shells, eight. That means they will have similar chemical properties, i.e., they all are on the lookout to borrow one electron.
The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
Why will an alkali metal often combine with a halogen nonmetal to form a compound?
Well, the "happy" number in chemistry is eight. And alkali metals have one valence electron while halogens have seven so when they combine, the combination has eight valence electrons. This means it is full.
How Manu valence electrons does fluorine have?
Fluorine is a chemical element in the halogen group. It's electron structure is 1s2 2s2 2p5. That means that it has 6 valence electrons.
How many valence electron does alkali metals have?
Alkali metals have one valence electron.
Hydrogen has how many valence electrons?
One. A hydrogen atom contains only one electron, and it is a valence electron.
