Hennig Brand was the first person recorded to have discovered a new element. Brand was a bankrupt German merchant who was trying to discover the Philosopher's Stone - a mythical object that was supposed to turn inexpensive base metals into gold. He experimented with distilling human urine until in 1649[3] he finally obtained a glowing white substance which he named phosphorus. He kept his discovery secret, until 1680 when Robert Boyle rediscovered it and it became public. This and related discoveries raised the question of what it means for a substance to be an "element".

In 1661 Boyle defined an element as a substance that cannot be broken down into a simpler substance by a chemical reaction. This simple definition actually served for nearly 300 years (until the development of the notion of subatomic particles), and even today is taught in introductory chemistry classes.

In 1914, Henry J. G. Moseley stuied X-spectrum of elements. From the experiment, he confirmed that proton number should be the basis for the periodic change of chemical properties instead of atomic mass. He arranged the element in order of increasing proton number in the Periodic Table. Each element discovered in different year. But modern Peridic Table use today is from Henry J. G. Moseley experiment in 1914.

There are 118 elements. The latest is Organesson(Og) It is an artificial element made in 2016.

Other elements such as copper and iron have been known since pre-history.

I suggest you look at the Periodic Table. The Periodic Table lists all the known elements, from Hydrogen to Organesson.

A good table will give the Atomic Number and Atomic Mass/Weight. On high-lighting each element it will give such data as MP , BP , Density, Appearance, physical state. , Isotopes, Possible date of discovery and discoveror.

The Royal Society of Chemistry (RSC>org) publishes a copy of the P.T. with all this data.

Hope that helps!!!!
