When elements react with other elements, they gain or loose electrons. Electrons are the reason that some elements react and others do not. Each element wants to have eight outer electrons. This is called the octet rule. (oct means eight). However, most elements do not have eight (except for the elements in the 18th column of the Periodic Table). The periodic table shows how many electrons each element has on its outer-layer. The last number of the column # (in the periodic table) is the number of electrons that the element contains in its outer-ring. For example, elements in the first column have one.
Another way is when substances burn and reach oxygen. This is called oxidation reaction.
There are many reasons why an atom will tend to gain or lose electrons. The atom is aiming to become more stable for example.
They become ions and have a charge. If an element like Na looses an electron it will become the sodium ion, Na+1.
Atoms gain or lose electrons in order to become stable, which usually means having a noble gas configuration.
to become stable, or like the noble gases
Lost because it is easier for the element to lose 3 electrons and become an octet than it is to gain 5 electrons.
it would gain electrons because itwants to be like another high powered element
It needs to lose, or gain, electrons.
to become stable
bcc it's the same
Generally metals lose electrons and nonmetals gain electrons.
Chlorine gain electrons.
No. Atoms of an element lose or gain electrons to form ions.
Lost because it is easier for the element to lose 3 electrons and become an octet than it is to gain 5 electrons.
lose 2
An element can either gain or lose electrons to achieve a noble gas electron configuration. Such an electron configuration gives an atom of an element a full outer shell, thereby making that element's ion nonreactive. Metals tend to lose electrons, and become cations, whereas nonmetals tend to gain electrons, and become anions. The amount of electrons an element gains of loses is based on the group/family the element is found in on the Periodic Table.

Ionic Bond is the answer SGT John
It needs to lose, or gain, electrons.
