why deuteron has no excited state?
8948
Deuteron has no excited state. It is because any excitation will easily to make the system break apart. ... Under the only force, the strong force in this system, proton and neutron are the same nucleon with different state. Thus, the parity are the same for proton and neutron.

no. is 0 suggesting that there is one s sub shell in the first energy level. Thus all other sub shells like p, d and f are absent. ... thus there are s and p sub shells in the 2nd energy level and d and f are absent.

It is not on the periodic table! Deuterium is simply Hydrogen with one extra neutron (i.e., 1 proton, but the same atomic weight as He). Its natural abundance (which is virtually nothing) is factored into the average atomic weight of H which as you notice is NOT exactly 1 amu).

They each have one single proton (Z = 1), but differ in the number of their neutrons. Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. The isotopes of hydrogen have, respectively, mass numbers of one, two, and three.

Deuterium. , also known as heavy hydrogen) is one of two stable isotopes of hydrogen (the other being protium, or hydrogen-1). The nucleus of a deuterium atom, called a deuteron, contains one proton and one neutron, whereas the far more common protium has no neutrons in the nucleus.

How do we distinguish between them? They each have one single proton (Z = 1), but differ in the number of their neutrons. Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. The isotopes of hydrogen have, respectively, mass numbers of one, two, and three.

Solution : The electronic configuration of the element palladium (Z=46) is [Kr]364d105s0. This means that it has no unpaired electron.

For diamagnetic character, there should not be any unpaired electron in the molecules formation. Here, for H2 the number of unpaired electron is 0. But in all other case there's an unpaired electron. Let it be H2- ,H2+ or He2+ ; there's an unpaired electron i.e, they are paramagnetic.

Deuterium is a hydrogen isotope consisting of one proton, one neutron and one electron. It has major applications in nuclear magnetic resonance studies. Tritium is a hydrogen isotope consisting of one proton, two neutrons and one electron.

As the other answers have suggested, Hydrogen has only one proton, no neutrons, and uncharged, has one electron. However note that in nature, free hydrogen is found as a diatomic molecule (H2). Therefore, a hydrogen molecule has two protons, and 2 electrons (which form the bond between hydrogen atoms).

The vast majority of molecules in a solution are solvent molecules, and most regular solvents are hydrocarbons and so contain NMR-active protons. In order to avoid detecting only signals from solvent hydrogen atoms, deuterated solvents are used where 99+% of the protons are replaced with deuterium (hydrogen-2).

The reason is very simple. EDX is related to the K-shells which are not the valence shell. H does not have a K shell, or , better to say, it has only a K shell in convalent bonding and this only electron is shared.

Deuterium – brief facts The isotope is denoted “2H” or “D”, and is normally known as “heavy hydrogen”. Deuterium is used in a number of conventional nuclear reactors in the form of heavy water (D2O), and it will probably also be used as fuel in fusion reactors in the future.

In ordinary water, each hydrogen atom has just a single proton in its nucleus. In heavy water, each hydrogen atom is indeed heavier, with a neutron as well as a proton in its nucleus. This isotope of hydrogen is called deuterium, and heavy water's more scientific name is deuterium oxide, abbreviated as D20.
