More than anything else it depends upon the number of electrons in the outer orbitals and how the electrons are filled.
The Periodic Table will give you a clue.
Column 1 (IA) is the Alkali metals (one S electron). Hydrogen gas, a non-metal is the only exception. These all can release an electron to become positive one ions.
Column 2 (IIA) is the Alkaline earths (two S electrons). Beryllium to Radium are all metals. These can easily give up two electrons (to get a +2 charge).
Columns 3 (IIIB) to 12 (IIB) which fill in the d electrons are all metals, as are the Lanthanide and Actinide Series (which fill in the f electrons).
This covers 80 metals out of 81 looked at. Columns 13 (IIIA) to 18 (VIIIA or 0) fill in the p electrons. Here we get a mixture of metals (toward the lower left) and non-metals (up and to the right), with metaloids bewteen.

Good question.
Metals are electropositive, which tend to lose electrons. In the periodic table, most of the elements are from d-block. All of these d-block elements are metals. This is due to their ability to lose electrons easily.
They lose electrons easily, because the differentiating electrons enter into the d-orbitals of inner shells and they cause shielding effect (reduction of nuclear attraction)over the outer electrons. Hence the outer electrons can be removed easily and hence the metallic nature.
And there are more d-block elements, because the the d-sublevel contains five d-orbitals which can accomadate 10 electrons.
Not only these but f-block elements are also metals due to same reasons sited above.
Finally the s,d and f and ofcourse some of the p block elements are metals as they posses big size and tendency to lose electrons.
I think u are happy with the answer.

There are more metals than nonmetals because more things in the world are made up of metals

Really it depends upon the number of electrons in the outer sheel and how the electrons are filled.The Periodic Table will tell you the answer.

a subatance is characterised by many factors
electronegativity,ionisation enthalpy,bond enthalpy,outer electronic configuration etc...satisfying all these conditions we have more metals than nonmetals..
