hell... ooo!!
The chemical properties of elements depend on an element’s electron configuration.
When the highest occupied energy level of an atom is filled with electrons, the atom is stable and not likely to react.
The chemical properties of an element
depend on the number of valence
electrons.An electron dot diagram is a model
of an atom in which each dot represents a
valence electron.
Elements that do not have complete sets of valence electrons tend to react. Some elements achieve stable electron configurations through the transfer of electrons between atoms. Each atom ends up with a more stable arrangement than it had before the transfer.
When an atom gains or loses an electron, the number of protons is no longer equal to
the number of electrons.
The atom is not neutral. An atom that has a net positive or negative electric charge is called an ion.
An ion with a negative charge is an anion. An ion with a positive charge is a cation. When an anion and a cation are close together a chemical bond forms
between them.
A chemical bond is the force that holds atoms or ions together as a unit. An
ionic bond is the force that holds cations and anions together.
An ionic bond forms when electrons are transferred from one atom to another.
Cations form when electrons gain enough
energy to escape from atoms.
The amount of energy used to remove an electron is called ionization energy. Compounds that contain ionic bonds are ionic compounds.
Ionic compounds can be represented by chemical formulas.
& hence chemical properties of electron depends upon ELECTRONS!!
