When chemical bonds form, thermal energy supplies some of the energy needed to remove electrons from metal atoms. Also, energy is released as the electron associates with another atom. This energy contributes to the removal of electrons from metal atoms too; both processes happen simultaneously (as the electron moves away from the metal, it moves closer to the other atom. Because of this, there is a lower activation for the process than there otherwise would be).
In some cases, the electron is not passed to another atom. This can occur when a high energy photon is absorbed, which ejects the electron from the metal.
most metals have few valence electrons and form +ve ions
Energy needed.....positive ions.
EXTRA CREDIT: Energy required to knock off valence electrons is called ionization energy
Metals lose electrons to form positive cations.

Metallic bonds involve free electrons delocalised over the metal. A very simple description is a sea of electrons with positivelly charged metal atoms.
The electrons are shared between the atoms. An ionic bond occurs between a metal and a non-metal. The metal donates one or more electrons to the non-metal, causing the metal to have a positive charge. When the non-metal accepts the electrons, it becomes negatively charged, thus resulting in an attraction between the two charged ions, and forming a bond.
During reaction of metals and non-metals, metal atoms tend to loose electrons and non-metal atoms tend to gain electrons. This transfer of electrons has a predictable offect on the size of the ions that form, and that predictable effect on the size is called the ionic size.
Its very simple!An ionic bond is where a metal atom transfers electrons to the non-metal atom, so that all atoms end up with a full outer shell of electrons. This will result in the formation of charged ions.
Ionic bonds are formed between metal atoms and non-metal atoms. The metal atoms lose electrons and form positive ions, but the non-metal atoms gain electrons and form negative ions. Since the atoms both now have opposite charges, they are attracted to each other and form an ionic bond.However, covelant bonds are formed between two or more non-metal atoms. The atoms share electrons rather than losing or gaining electrons from each other.

A metal is normally viewed as cations in a sea of delocalised electrons. It is the metal atoms which donate their valence electrons to the sea of delocalised electrons.
When a metal reacts with a non-metal, the electrons move from the metal to the non-metal. This is because the metal can achieve valence when it loses the electrons in its outer shell. The non-metal can also achieve full valence by gaining the electron in its outer shell.
An ionization suppressor is a salt of an alkali metal added to suppress ionization of an analyte. The alkali metal is easily ionized resulting in a flux of electrons which shift the ionization equilibrium of analyte towards formation of atoms.
