The closer the number of valence electrons is to the number required to completely fill or deplete its outer shell the more likely the atom is to react.
With other electrons in an atom the shells are full and they have little if any affect on the reactivity of an atom. Valence electrons are the only electrons that are available to be shared/transferred in a bond.
What else can I help you with?
How do valence electrons differ from the other electrons in an atom are the outermost energy?
They do not differ in any way, except they are the 1 to 8 electrons in the highest energy ground state orbitals of that atom.
How many valence electrons does a neutral oxygen atom have?
A neutral atom of oxygen would have 6 valence electrons.
Is an electron a type of chemical bond?
No. Electrons are part of the atom. For example, when two atoms come together and one has 6 valence electrons and the other has 2 valence electrons, the atom with the 2 valence electrons might get bonded to the other atom with 6 valence electrons because the atom with 6 valence electrons wants to have 8 valence electrons to fill its outer shell. You might think electrons are bonds, they are not. They are what cause atoms to bond but are not bonds.
How many valence electrons does a nitrogen atom have then a carbon atom?
nitrogen has 5 valence electrons. carbon has 4 valence electrons.
What are valence electron?
Valence electrons are the electrons in the outer-most shell of the atom. These are typically the electrons involved in forming bonds with other atoms (as opposed to the other so-called "core" electrons which do not interact much with other atoms or molecules.)See the Related Questions links below for more information and for how to count the valence electrons of an atom.Any electrons located in the outer shell of an atom are known as valence electrons.Valence electrons are electrons present in the outermost shell of an atom.
How many valence electrons are in an atom of magnesuim?
There are 2 valence electrons in an atom of magnesium. There are 5 valence electrons that are in an atom of phosphorus. There are 4 valence electrons that are in a silicon atom.
Do compounds have valence electrons?
Yes, compounds have valence electrons. Valence electrons are the outermost electrons of an atom involved in chemical bonding, and they are also involved in forming compounds by interacting with other atoms' valence electrons.
Which electrons are the valence electrons of an atom?
The electrons farthest away from the nucleus are the valence electrons of an atom.
