We don't know exactly, but mathematical models predict it was early. Protons and Neutrons had already fused to produce the current Hydrogen/Helium ratio before matter and radiation decoupled, leaving what is now the 3K blackbody radiation.

What is the name of the particles that are protons neutrons and electrons?

The particles that include protons, neutrons, and electrons are collectively known as subatomic particles. Protons and neutrons are categorized as baryons, while electrons are classified as leptons. Together, these particles make up the atoms that form all matter in the universe.


How do protons form?

Protons are formed from quarks, which are fundamental particles. Specifically, a proton is composed of three quarks: two up quarks and one down quark, held together by the strong force mediated by gluons. During the early moments of the universe, quarks combined to form protons and neutrons as the universe cooled down after the Big Bang. This process is part of nucleosynthesis, where protons and neutrons later combine to form atomic nuclei.


What happened 3 mintues after the big bang?

Three minutes after the Big Bang, the universe had cooled down enough for protons and neutrons to begin combining to form the first atomic nuclei, a process known as nucleosynthesis. This marks the beginning of the era of light nuclei formation in the early universe.


Is the nucleus made of protons and neutrons that have a positive charge?

The nucleus of an atom is composed of protons and neutrons, but only the protons carry a positive charge. The neutrons do not carry any charge.


What is the building blocks of matter that's made up of protons electrons and neutrons?

The building blocks of matter are atoms, which consist of protons, neutrons, and electrons. Protons and neutrons form the nucleus at the center of the atom, while electrons orbit around the nucleus in various energy levels. The arrangement and number of these subatomic particles determine the chemical properties of the element. Atoms combine to form molecules, which make up all matter in the universe.

Protons neutrons and electrons combine to form what?

Protons, neutrons, and electrons can form any type of atom on the Periodic Table of Elements.The amount of protons determine what type of element an atom is.If the number of neutrons differ from the stable amount it should have, the atom is known as an isotope.If the amount of electrons differ from the amount of protons, the atom is known as an ion.

Is the number of protons the mass?

Not necessarily. An estimated form of atomic mass is protons + neutrons.


What are the three essential parts of an atom?

Protons, Neutrons and Electrons. Protons and Neutrons form the nucleas, surrounded by a cloud of Electrons.
