How do the number of valence electrons affect how likely a substance is to react with another substance?

The number of valence electrons is the number of electrons in the outer energy ring of an atom. The most electrons the first energy level of any atom can hold is two. The rest is 8. If the outer energy level is full, the atom will be less reactive because it cannot add any more electrons to it's current outermost energy level. If it only needs one or two more electrons to fill it's last energy level or if it only has one or two in it's last energy level, it will be more reactive, because it only needs to gain a few or lose a few to be full.

∙ 11y agothe valence electrons are either shared between atoms, or valence electrons are taken by one ion from the other, bonding the atoms together, which is what a chemical reaction is.

How does the number of valence electrons affect an element?
The number of valence electrons affect the type of bond formed by an atom with other atoms as it determines the number and type of atoms it needs to bond with. An atom with one valence electron, for example, will bond with one atom that needs one electron.
How are valence electrons special?
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.
How do valence electrons affect how atoms bond?
if atom has enough valence electrons to all pair up like noble gases do they are resistant to change and are not able to bond with any other atom however if there are not enough valence electrons to all pair up the unpaired electrons are unstable and are able to bond with other atoms to share their electrons.
How many valence electrons does each Atom have and how does that affect the type of bond in each molecule?
there is no one answer to this question. It all depends on where the atom is in the Periodic Table.
Define valence electron?
A valence electron is an electron in the outer shell (or cloud or orbital as it is sometimes referred) farthest away from the nucleus. These are the electrons that are transferred or shared in chemical bonding. (A "full" outer shell refers to atoms with (usually) 8 electrons in its outer shell.)
How does the number of electrons in energy levels affect bond formation?
Chemical bonding is occurred from the participation of valence electrons. Valence electrons are located in the topmost energy level of an atom.
How do valence electrons affect the way a element reacts?
When an element with few vakence electrons comes in contact with ine that has many valence electrons the reaction is more violent and vice versa.
How are valence electrons differ from other electrons in an atom?
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.

How does the number of valence electrons affect an element?

Why are valence electrons significant?
They are significant because they determine what element would be in a specific block (s,p,d,f).

What is the outer most energy level of an atom?
This is the valence shell and is involved in bonding e.g. the sharing or loss of electrons to form a molecule or giant structure. Inner shells do not take part in bonding though their shielding effect and repulsion does affect the loss and gain of electrons from this shell.
How do valence electrons affect how atoms bond?
if atom has enough valence electrons to all pair up like noble gases do they are resistant to change and are not able to bond with any other atom however if there are not enough valence electrons to all pair up the unpaired electrons are unstable and are able to bond with other atoms to share their electrons.
Does the amount of protons an element has affect chemical bonding?
Yes and no; the number of protons determine the valance number of electrons. The valence level of electrons and how full/empty it is largely determines an elements chemical behavior. I would say that valence electrons are the main determinant, but that is predetermined by protons.
Know how valence electrons affect the Noble Gases?
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
How many valence electrons does each Atom have and how does that affect the type of bond in each molecule?
there is no one answer to this question. It all depends on where the atom is in the Periodic Table.
