Why is an atom with fewer electrons in the outer shell more reactive?

That isn't really true. What makes atoms more reactive is if their electronic configuration is nearly that of a noble gas -- in other words is either has just one or two electrons less or more than a noble gas.So elements with either 1, 2, 6 or 7 valence electrons tend to be especially reactive.
so the guy who gave the first answer doesnt know what hes talking about.

Is an atom that has six electrons stable?
No, an atom with six electrons will try to react with another atom to gain two more electrons. Actually the fewer electrons the atom needs the more reactive it will be unless it has exactly eight valence electrons in its outer shell like a noble gas(He, Ne, Ar, etc.) Hope this helps!
What electrons are the outer most shell of electrons in a atom?
Valence Electrons
Why do halogens react so easily with Alkali Metals?
The electron configuration is why they react. The Alkali metals have one electron in their outer shell and to complete their outer shell need 7 more electrons. They can give, take or share electrons with other atoms. This is when the Halogens come in handy. The Halogens have 7 electrons in their outer shells, and need one more to complete the outer shell. These can react very easily because they have both the perfect amounts to fill their outer shells and become compounds. Other atoms with other amounts to become atoms not ions needs another element to react with. Hope this helps, Matt.
What is similar about the outer shell of electrons in the alkaline earth metal family?
The outermost shell contains two electrons.
Does barium have two electrons in its outer p orbitals?
Yes, barium is divalent with two electrons in the outer shell.
Are atoms with eight electrons in the outer shell not reactive at all?
stable and chemically nonreactive, or inert.
What makes atom reactive?
an incomplete outer shell of electrons
If an element has a total of 86 electrons is it inert reactive or non reactive?
This is radon, it has a full outer shell of electrons, so it is technically non reactive
Elements in the second group have 2 outer shell electrons and are also very reactive They are called?
Elements in the second group have 2 outer shell electrons and also very reactive. What are they called?
Why is noble gasses the least reactive?
they are unreactive as they have a full outer shell of electrons
An electron configuration that is not chemically reactive?
Where there are 8 electrons in the outer shell so a full shell. Elements are reactive when they need to lose or gain an electron. The noble gases are unreactive as they have a full outer shell.
How many electrons are in the outer shell of caesium?
Just 1 making it very reactive.
When does a liquid cause harm?
if it is highly reactive with substances in a place which people are or inside the body bit of a general question but if something is harmful it will be reactive which means it does not have a full outer shell of electrons and will want a full 8 electrons in it's outer shell to be stable so it will react with anything which will enable it to complete it's outer shell.
How many electrons are in the outer energy level of the atoms of alkali earth metals?
There are two electrons on the outer shell which means they are pretty reactive. (make bonding easier)
Does two valence electrons is a reactive or non reactive?
The outer shell of an atom is most stable or non reactive with 8 electrons. 1 or 2 valence electrons would be reactive. It also would depend if it's bonded with another element.
How do you determine how reactive an element is based off its atomic number?
the reactivity of depends on the number of its outer shell electrons. one all outer shell electrons are there then there is little reactivity. If the atomic number is 19 then the element will 19 protons and 19 electrons. this means it has 2 electrons in the 1st shell 8 in the second 8 in the 3rd and 1 in the last. as it only has one it will be very reactive =)
If an atom has fewer than 4 electrons in its outer shell does it looses electrons gain electrons or both?
The atom wants to have eight or full electrons in its outer valence ring... so if it has four electrons in its outer shell it has the choice of loosing four electrons or finding four electrons somewhere else (whichever is the easiest for it to bond with).
