No, hydrogen atom is highly unstable itimmediately combines with another hydrogen atom to gain the stability the amount of heat released confirms the instability of one hydrogen atom. [2H] = H2 (-105 K.cal/mole)
That's an interesting question.
Let's get the easy answer out of the way first: monatomic hydrogen is not stable chemically.
Now the more complicated answer about stability in the "radioactive" sense. Bear with me here.
There are three isotopes of hydrogen.
The heaviest, tritium, is 3H. It has one proton and two neutrons. It is an unstable nuclide and decays via beta decay to 3He with a half-life of about 4500 days.
The second heaviest, deuterium, is 2H. It has one proton and one neutron. It is considered a stable nuclide, but see the caveat below.
The lightest (and by far the most common) is 1H. It consists of a single proton, and so it may be a stable nuclide... some theories predict that it's possible for protons to decay. However, experiments have shown that even if it is possible, the minimum value for the half life is at least 6 x 1033 years, which is over 4 million million million million times longer than the current age of the universe, so by any practical standard, it's stable.
If protons decay, then ultimately no atom is stable, and they will eventually all decay (neutrons are known to be unstable, with a half-life of about 10 minutes, unless they are bound in an atomic nucleus - it's possible that being bound into a nucleus could increase the proton's stability as well, but we just don't know).
Yes, Chlorine atom is stable
he2 is a fatty. He atom is a inert gas. so it can not react with any other atom or molecules to form any compounds.so He2 can't exist. ANOTHER ANSWER: Helium atom has only one shell i-e K-shell which can accommodate a maximum of two electrons which it already has. therefore Helium atom does not need any more electrons to become stable as it is already stable by duplet rule. Thus helium atom does not combine with another helium atom and hence exists as He and not He2.
Hydrogen is an atom but the hydrogen molecule is diatomic.H is a single Hydrogen atom, and H2 is a molecule.
a hydrogen bond is a type of weak chemical bond. It is formed between the slightly positively charged hydrogen atom of one molecule and a slightly negative charged atom of another. A strong would be a covalent bond (it forms when atoms share electrons in order to become more stable)
There are three sets of interactions in this system: The 4th explains: Why? # Repulsion between the two electrons (one interaction of this type) # Repulsion between the two nuclei (one interaction of this type) # Attractions between each electron and nucleus (four separate interactions of this type # Therefore a single hydrogen atom is less stable and requires less energy to break down.
A stable atom of hydrogen (H)
Two.
In simple terms, an atom with an unstable nucleus will decompose because the protons and neutrons breaking away from one another. In a hydrogen nucleus, which consists only of a single hydrogen atom, there is nothing for it to break away from.
A hydrogen atom is only a proton and an electron. Beyond that the neutron seems to keep the nucleus together and stable. Maybe a better question is, "What is the difference between a hydrogen atom without an electron and a proton?"
hydrogen, helium, lithium, and beryllium
There are two atoms with two neutrons. One is hydrogen-3 which is radioactive. The other is helium-4 which is a stable and inert atom.
There is a concept in chemistry called valence, which is the number of bonds an atom can form to make a stable compound or molecule. Oxygen has a valence of 2, meaning it needs 2 bonds to form stable molecules. Hydrogen has a valence of 1. So, to satisfy the valences of both elements, two hydrogen atoms bond to one oxygen atom.
They have enough energy produced to fuse four hydrogen atoms into a helium atom.
The atom with an atomic number of 1 is Hydrogen. Hydrogen only has one electron and is very unstable because it is very close to the nucleus and has an incomplete valence shell holla back
Stability isn't determined by the first energy level. The only atom with less than two is hydrogen. It is a very stable atom...reactive in that it will attach to anything, but it will always be hydrogen. The atoms that readily decay (the radioactive ones) all have full first orbitals.
Individual hydrogen atoms are stable in so far as they do not decay, they are however very reactive chemically and they can easily become stabilized by bonding two hydrogen atoms each other to form a hydrogen molecule. Meanwhile, hydrogen reacts with many other elements including metals, metalloids and non metals.
