What happens to a valence electron in a metallic bond?
Valence electrons in a metallic bond are delocalized and can move freely within the metal atoms. This gives metals their malleability and luster.
What happens to the electron cloud with increasing periods number?
The electron cloud increases the amount of valence shells it has with the increase of electrons in the atoms
What is the family of very reactive groups of mostly nonmetals whose atoms gain or share one electron in chemical reactions?
The Halogen family.All but one of the halogens are nonmetals, and all share similar properties. A halogen atom has 7 valence electrons and typically gains or shares one electron when it reacts.Hope this helped.
What metals react with other metals what happens to the valence electrons of the metal atoms?
== == When metals react with other elements, the atoms of the metals give up their 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 many valence electron does halogen have?
Halogens each have 7 valence electrons.
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.
How many electrons are in the outer electron level of the halogen?
7 electrons are on the outer (valence) shells of all halogens
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 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.
When this element combines with other elements it usually gives up its one valence electron?
Could be many different elements
Which electron has seven valence electrons?
Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine.
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.
What happens to sodiums valence electron when sodium bonds with chlorine to form table salt?
The electron is transferred to chlorine.
What happens when you lose a valence electron in your overall charge?
The atom becomes an ion
What happens when a chlorine atom gains an electron in its valence shell?
It becomes an ion.
The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
