Metals as found in the Periodic Table have no "extra" electrons. They are electrically neutral because they have the same amounts of protons and electrons or + and - charges respectively.
However metals react with non-metals to form Ions, cations to be more precise, in this case they actually lose electrons resulting in a positive charge. In other words, metals never have "extra" electrons, they either have a neutral charge or they are lacking electrons and have a negative charge.

How many valence electrons are in alkali metals?
Alkali metals have 1 valence electron.
How many valence electrons do the alkali metals have?
Alkali metals have 1 valence electron.
Do alkali metals contain 7 valence electrons?
No. Alkali metals have one valence electrons. Halogens have 7 valence electrons.
How many valance electrons do rare earth metals have?
Rare earth metals typically have 2 valence electrons.
What are metals that have 2 valence electrons?
alkaline earth metals (group 2 elements) have two valence electrons
How many valence electrons are in alkali metals?
Alkali metals have 1 valence electron.
How many valence electrons are in alkaline earth metals?
Alkaline earth metals have 2 valence electrons.
How many valence electrons in alkaline earth metals?
The alkaline earth metals are those in the same group as calcium; they have two valence electrons.
How many valence electrons do the alkali metals have?
Alkali metals have 1 valence electron.
Do alkali metals contain 7 valence electrons?
No. Alkali metals have one valence electrons. Halogens have 7 valence electrons.
How many valence electrons are in iridium?
2 valence electrons are in iridium because iridium is a transition metal. Most transitions metal would have 2 valence electrons because the group before the transition metals are the alkaline-earth metals which contains 2 valence electrons in that group making the transition metals have 2 valence electrons.
How many valence electrons do alkaline earth metals have?
The alkali earth elements have TWO valence electrons.
How many valence electrons do Cooper have?
Copper (Cu) has 2 valence electrons. It is located in the middle group of elements, called Transition Metals, and all transition metals have 2 valence electrons...hope that helped! =D
Does electrons in metals have few or many valence shell?
yes
How many valance electrons has alkali metals?
1 valence electron in alkali metals.
What do valence electrons in metals do?
Metals lose electrons in a chemical reaction.
What are metals that have 2 valence electrons?
alkaline earth metals (group 2 elements) have two valence electrons
