This atom is hydrogen.

how many numbers of atom are present in one gram of oxygen
The atomic No. shows an atoms position in the Periodic Table. The Atomic No. shows how many protons are in the atom. The atomic No. shows how many electrons in a NEUTRALLY charged atoms. Do NOT confuse with Atomic Mass. The Atomic Mass is the sum total of all the protons and neutrons (collectively nucleons) in the nucleus of an atom.
There is 1 hydrogen atom and 1 chlorine atom in Hydrogen Chloride.
Neutrons are protons are present in the nucleus of an atom.
Particles that are never present in an atom include free electrons (outside the nucleus), neutrinos, and positrons. These particles do not form part of the structure of the atom itself.
The subunit of an atom that is present in equal numbers is the electron. In a neutral atom, the number of electrons equals the number of protons, balancing the positive charge of the nucleus. This equality maintains the overall electrical neutrality of the atom.
Protons and neutrons are present in the nucleus. Electrons are present in orbits of an atom. Where as proton are located at centre of the nucleus.
The isotope hydrogen-1 don't contain neutrons.
1 Hydrogen atom is present in H2SOn4.
Why helium, of course!
