What else can I help you with?
Which came into existence first atoms or quarks?
The currently accepted model of the Big Bang predicts that the early universe was composed of a quark-gluon plasma. After it cooled, baryons could form (baryons are particles like protons and neutrons which are made of quarks), and some time after that atoms could form. If you mean which was DISCOVERED first, atoms, by at least a couple of centuries.
Where was energy first made?
Basically, all energy that currently exists in the Universe was there from the start - i.e., from the moment of the Big Bang. It is not currently known what caused the Big Bang, or where the energy came from.
What molecule do scientists believe came first in the evolution of life on Earth?
Scientists believe that the molecule that came first in the evolution of life on Earth is RNA (ribonucleic acid).
What element shows the number of protons in its nucleus?
Please note that every property of an element depends on protons so one property is often hard to sort out from another since each property has its own trends in relation to the number of protons (atomic number). The first property that indicates the number of protons is a nanoscopic one, atomic width. A property that can indicate the relative number of protons is density. That is chemical density not structural density. Air voids in a solid can make the density seem smaller. Most solids (that is, true solids devoid of air gaps and porosity) are heavier than water. So if you wanted to find density differences in known solids (and reative atomic numbers) you would hit the object with x-rays and record the relative amounts that came through to the exposure film. If you have access to a Scanning Electron Microscope using primarily the back scatter contrast method can give you an image depicting relative differences in density. Remember though it must be a true solid. Many elements have isotopes which essentially are more dense atoms withe the same atomic number. These elements are still relatively close to the non-isotopic element since there is no absolute way to.
Who Evidenced the existence of subatomic particles?
For the particles in the atom: Neutron: James Chadwick, 1932 Electron: J. J. Thomson, 1897 Proton: Ernest Rutheford, 1919
Which came first atoms or electrons?
Of the two, electrons. (Protons had to form, perhaps from quarks, before the first atoms could form and the temperature had to be cool enough for protons and electrons to come together to form hydrogen.)
What is a first organized particle?
The earliest organized particles are believed to be protons, neutrons, and electrons that formed shortly after the Big Bang during the process of nucleosynthesis. These particles eventually came together through gravitational forces to form the first hydrogen and helium atoms.
Did Mendeleev know about protons neutrons and electrons?
No, Mendeleev did not know about protons, neutrons, and electrons. He is best known for creating the periodic table of elements based on the properties of the elements without knowledge of the atomic structure. The discovery of protons, neutrons, and electrons came later with the development of atomic theory.
Were protons and neutrons in existence immediately after big bang?
We weren't there; NOBODY was. There was nothing at the moment of the Big Bang, and we cannot be certain of what came into existence or when in the seconds, minutes or hours following the event. So, "immediately"? We believe - based entirely on poorly-understood mathematical theories for which no practical test is possible - that "matter", in the sense of protons, neutrons, electrons, and their corresponding antiparticles, probably did come into existence within a few seconds of the event.

Does the understanding and development of atoms have anything to do with nuclear applications?
Yes, physics first came to understand atoms and that they had nuclei and 'shells' of electrons, and later it came to be understood that the nuclei were composed of protons and neutrons. Nuclear applications only followed this second stage, but the first stage ws essential too.
What happened at each critical point of the big bangs timeline?
First the grand unified force split up into the four current forces. Then quarks and electrons formed from energy. Quarks came together to form protons and neutrons which came together to form the first atomic nuclei. After the Universe cooled off for a while, electrons bonded with the nuclei to form the first atoms. The first elements were hydrogen and helium. See the related link for a much more detailed explanation.
When did Earth from?
it came from god or if you scientific it came from the big bang
What came first the planet or the big bang?
The 'Big Bang' was the start of our universe, so before this event, there was nothing (although some scientists believe there may be other universes). So, the stars, including our sun, came later, and then the planets.
When was helium invented?
Helium is a naturally occurring chemical element therefore it can never have been invented but instead it was discovered. Though the above is true, Helium is the second lightest element in nature, right after Hydrogen, the lightest element. During the first 300,000 years after the Big Bang, ionized gases (plasma) combined together quarks and electrons to create Hydrogen, then eventually Helium, Carbon, Oxygen, and so on. So by "invent", I took it as you mean when was it first created in nature. It would have been first created when the first protons and electrons got together to mingle with neutrons, whom of which came later on, in huge molecular clouds that then created the first proton-stars.

What describes a neutral atom?
An atom is composed of these sub particles: protons, nuetron, and electrons. Inside the nucleus there are protons (positively charges) and nuetrons(nuetrally charges). Ouside of the atom's nucleaus are electrons (negatively charged). An atom is said to be nuetrally charged if there are the same number of protons and electrons.
