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 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.
