An atom that has two protons is?
The answer is NONMETALS.
beryllium has four protons alpha particle or Helium has two protons.
Let's see, 1hydrogen, 2helium, 3lithium, 4beryllium, 5boron, 6carbon, 7nitrogen, 8oxygen. Eight protons in one atom of oxygen. Oxygen is diatomic, so there would be 16 p…rotons in a typical oxygen "molecule."
It is helium, specifically the helium-4 isotope, that is composed of two protons and two neutrons.
None of the elements of the periodic table have the same number of protons. All elements have their own unique atomic (proton) number which defines how many protons that …element has in its atoms. Just a note that the atomic number is also called the proton number. To know which number is which the atomic number is always smaller. The Atomic number gives both the proton and electrion number as these most be the same due to the charges for it to be an atom.
The atom in a normal state would have two protons to match the two electrons, making the overall charge zero. If the atom is an ion, it would have an mismatched number of prot…ons and electrons, giving it a positive or negative overall charge.
We don't find an atom with only two protons in its nucleus. Only the atom of hydrogen-1 has no neutrons. But there is something about a proton pair we might want to consider. … In stars, we find two protons fused in what is called a proton-proton chain reaction, but one proton immediately undergoes beta minus decay and becomes a neutron. We'll then see a hydrogen-2 nucleus (a proton and a neutron) in the place of the two protons. This isotope of hydrogen will undergo further fusion reactions in stellar nucleosynthesis.
An atom with two protons is a helium atom .
It would by definition be Helium (atom number = number of protons = 2) but the nucleus of the stable isotope 4He also contains 2 neutrons (the mass number = total number of p'…s and n's = 4)
No protons and neutrons cannot be shared by two atoms, because they are in the nucleus where no interactions occur. Interatomic forces only happen between electrons of differe…nt atoms
