Hydrogen was the first.
Hydrogen as the atomic number 1 and promethium has the atomic number 61.
Hydrogen was first discovered by Henry Cavendish in 1766 in England. Antoine Lavoisier is considered the "father of hydrogen" for his work in recognizing hydrogen as an element and coining its name.
The first element to be discovered was probably copper or gold. They would have been discovered by hunter-gatherers or early farmers. Its discovery cannot be credited to any single person.
Hydrogen, H2, was first generated and described by Paracelsus, who was T. Von Hohenheim (1493 to 1541). He reacted strong acids with metals to produce it. Credit for the discovery of hydrogen is usually ascribed to Henry Cavendish, who produced it, discovered it burned and produced water upon combustion, and also proposed it was a unique element, which he did in 1776. A link can be found below.
Hydrogen is not considered a metal. It is a non-metal and is the first element on the periodic table. In its pure form, hydrogen exists as a diatomic gas and is the most abundant element in the universe.

It was first discovered by Jacob A. Marinsky, along with a few other scientists in 1944. But he did not make his claim of Promethium until 1946. The place Promethium was first discovered is still unknown to me...
Promethium was identified and prepared for the first time in 1945, at Oak Ridge, USA by Jacob A. Marinsky, Lawrence E. Glendenin, Charles D.Coryell, Harold G. Richter.

The sixty first element in the periodic table of elements is promethium. It is a rare earth metal that is not found naturally on Earth and is typically produced in nuclear reactors.
Plutonium
Ekasilicon (Mendeleev's name for the element below Silicon, 1869) is named germanium since it was discovered (1886).Eka (from Sanskrit) means 'first' for first element downwards.
Promethium was discovered in 1945-47 in burned uranium fuels as a fission product.
The first element, hydrogen, was discovered in 1766 by English scientist Henry Cavendish through the reaction of metals with acids, producing a gas that he called "inflammable air." This gas was later recognized as hydrogen by another scientist, Antoine Lavoisier, in 1783.
Helium is the element named after the Greek sun god Helios and was first discovered in the spectrum of the sun during a solar eclipse in 1868 by French astronomer Jules Janssen and British astronomer Joseph Norman Lockyer.
