Yes. Most hydrogen atoms only have a single proton in the nucleus, but the hydrogen isotopes deuterium an tritium have one and two neutrons respectively.
yes (except for the two isotopes of hydrogen).
Yes, a neutron is smaller than an atom. Neutrons are subatomic particles found within the nucleus of an atom, along with protons, and are about the same size as protons. Atoms consist of a nucleus made up of protons and neutrons, surrounded by electrons in orbit.
Yes, a neutron has more mass than a proton or electron.
Heavy water is formed from an isotope of Hydrogen called Deuterium which is 1 proton and 1 neutron whereas a normal hydrogen atom is only 1 proton. The extra particle causes the atom to have more mass and causes it's density to be greater than that of water
No partial or complete atom has anywhere near 12,000 times the mass of a hydrogen atom. The mass of the hydrogen atom is 1 atomic mass unit (AMU), corresponding to the single proton in its nucleus. The largest, most massive atom that presently occurs naturally on Earth is that of Uranium. The heaviest form of Uranium has 238 protons and neutrons in its nucleus, for an atomic mass of around 238. All of these mass numbers correspond to the number of protons and neutrons in the nucleus. The electrons surrounding the nucleus are largely ignored, for a few reasons: -- Electrons come and go, get added to and separated from atoms, rather easily. -- 1 proton or 1 neutron have as much mass as about 1,840 electrons, so a few electrons more or less doesn't make much difference in the mass of an atom. -- The most complex atom ... Uranium again ... normally has only about 92 electrons, which amounts to only about 5 percent of one proton or neutron, so they don't have much impact on an atomic mass of 238 .
yes (except for the two isotopes of hydrogen).
The pair form a hydrogen atom.There is a fallacy that's taught about this pairing, which is that the electron-proton pair form a neutron. See my answer to the question "What particle has the same mass as a hydrogen atom?" for more details about this, and why it is wrong.
It means that a deuterium atom is present instead of a hydrogen atom. Deuterium is an isotope of hydrogen, meaning that it contains one more neutron in the atomic nucleus. Hence, it is heavier than hydrogen.
Yes, a neutron is smaller than an atom. Neutrons are subatomic particles found within the nucleus of an atom, along with protons, and are about the same size as protons. Atoms consist of a nucleus made up of protons and neutrons, surrounded by electrons in orbit.
The term for the situation when an atom has more neutrons than protons is called neutron excess or neutron-rich.
Yes, a neutron has more mass than a proton or electron.
None. A hydrogen atom has one proton and one electron (no neutron). Removing the electron leads to just a proton, no electrons.
Heavy water is formed from an isotope of Hydrogen called Deuterium which is 1 proton and 1 neutron whereas a normal hydrogen atom is only 1 proton. The extra particle causes the atom to have more mass and causes it's density to be greater than that of water
Adding a neutron to an atom's nucleus increases the atom's mass by the mass of the neutron itself. Neutrons are more massive than protons, so adding a neutron will increase the atom's total mass without changing its charge.
A hydrogen atom can not form more than one bond, because a hydrogen atom contains only one electron.

Yes and no, Hydrogen (naturally 1 proton, 1 electron, 0 neutrons), has an isotope (variation, with a different number neutrons), called Deuterium with 1 proton and one neutron. Deuterium composes less than 0.02% of the worlds Hydrogen.
