I assume you mean "more neutrons than protons". It really depends what metal you are talking about. The lightest metal is lithium; it has 3 protons. One of its naturally occurring isotopes has 3 neutrons, another has 4 neutrons. In the case of heavier elements, the ratio of neutrons to protons increases; this is not directly related with the elements being "metals", just with the fact that they are heavier elements. The general idea here is that for heavier elements, the repulsive forces between protons become larger; more neutrons are then needed to provide stability, since protons and neutrons attract one another using the strong force, but don't have an electrostatic repulsion.

How many protons and neutrons are used in an atom?
"Used" is the wrong term to be used in this case. An atom is MADE up of protons,neutrons and electrons. Also, the number of protons or neutrons present in an atom depends on which atom is it or of which element it is.
