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.
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.
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.
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.
Every nucleus (except for Hydrogen) consists of protons and neutrons. The hydrogen nucleus is only a proton.
The nucleus of an atom is made up of protons and neutrons.
Atomic nucleus is formed from protons and neutrons.

the nucleus
The protons and neutrons are grouped together in the nucleus. The electrons form a cloud around the nucleus.
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.
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.
Boron is an atom or element, and it contains protons, electrons, and neutrons.
Not necessarily. An estimated form of atomic mass is protons + neutrons.
Protons, Neutrons and Electrons. Protons and Neutrons form the nucleas, surrounded by a cloud of Electrons.
Every nucleus (except for Hydrogen) consists of protons and neutrons. The hydrogen nucleus is only a proton.
Protons, neutrons and electrons are found in the atom. The protons and neutrons form the nucleus. Electrons orbit the nucleus. Protons are positively charged, neutrons have no charge and electrons are negatively charged.
The carbon-12 isotope has 6 protons and 6 neutrons. This isotope is the most stable and abundant form of carbon.
