During the 1880s and '90s scientists searched cathode rays for the carrier of the electrical properties in matter. Their work culminated in the discovery by English physicist J.J. Thomson of the electron in 1897.During the 1880s and '90s scientists searched cathode rays for the carrier of the electrical properties in matter.

When was the first electron formed?

How were the first electrons created?
The Big Bang at first produced a number of subatomic particles. These condensed to form electrons and protons. Very soon, a proton and an electron met, and formed a hydrogen atom.
Who discovered electron?
J.J. Thomson J.J. Thomson decided to find out for sure. Thomson was a physics professor at Cambridge University in the UK. He placed cathode tubes in electric and magnetic fields.
What is the first element to be created?
Hydrogen Hydrogen is believed to be one of three elements produced in the so-called Big Bang, the others being helium and lithium. It is the most abundant element in the universe, making up 75% of normal matter by mass and more than 90% by number of atoms.
What was the first particle in the universe?
The first entities thought to emerge were quarks, a fundamental particle, and gluons, which carry the strong force that glues quarks together. As the universe cooled further, these particles formed subatomic particles called hadrons, some of which we know as protons and neutrons.
Who in 1897 discovered the electron?
Joseph John “J. J.” Thomson In 1897 Thomson discovered the electron and then went on to propose a model for the structure of the atom. His work also led to the invention of the mass spectrograph.
Who named the electron?
G. Johnstone Stoney he word "electron," coined by G. Johnstone Stoney in 1891, had been used to denote the unit of charge found in experiments that passed electric current through chemicals. In this sense the term was used by Joseph Larmor, J.J. Thomson's Cambridge classmate.
Which element is the oldest?
The oldest chemical element is Phosphorus and the newest element is Hassium.
What’s the oldest element in the universe?
The first elements — hydrogen and helium — couldn't form until the universe had cooled enough to allow their nuclei to capture electrons (right), about 380,000 years after the Big Bang.
