This type of interaction form the covalent bond, for example between nonmetals.
The other common type of bond is ionic.
When elements combine to form compounds, electrons are shared, transferred, or localized between the atoms. This interaction helps to stabilize the atoms by completing their outer electron shells according to the octet rule. In covalent bonds, electrons are shared between atoms, while in ionic bonds, electrons are transferred from one atom to another.
It what happens when elements don't obey the octect rule, i.e. elements that have more than eight electrons in their outermost shell. It what happens when elements don't obey the octect rule, i.e. elements that have more than eight electrons in their outermost shell.
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
The pairs of electrons are shared between atoms.
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
The electrons between the two elements aren't shared equally and slightly polarizes both sides, or gives it a positive or negative charge.
all elements want to have a full valence shell and when an atom loses electrons it is said to become a cation.
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
Cations are formed when elements lose electrons. Then they get positively charged.
A neutral atom of a chemical element has a constant number of protons and electrons; loss or gain of electrons transform this atom in an ion.After the change of the number of protons the identity of the atom is lost.
