As Deuterium and Tritium are both merely isotopes of Hydrogen and not elements in their own right, they both have an atomic number of 1, just like Hydrogen (Hydrogen-1).
Deuterium (Hydrogen-2) has an Atomic Mass of 2, and Tritium (Hydrogen-3) has an atomic mass of 3.
What else can I help you with?
What is the difference between H2 and H1 isotopes?
They have different numbers of neutrons and therefore different atomic masses. Hydrogen-2, with 1 protons and 1 neutron has an atomic mass of 2. Hydrogen-1, with 1 proton and no neutrons has an atomic mass of 1. (By the way, the accepted way of writing these symbolically if you can't use subscripts is to put the number first, vis: 2H)
How cant you tell isotopes of the same element apart?
You can tell isotopes apart by the difference in there atomic mass numbers. Take for example the isotope Carbon-12. Carbon is the element name and 12 is the atomic mass of the element. The atomic mass number can (most?) always be changed, but the the atomic number ( the number above the Element symbol on the Periodic Table) cannot. Remember: The number of protons add by the number of neutrons equals the atomic mass number. The proton number = the atomic number, as of the number of electrons= the atomic number; hence the atomic number= number of proton = number of electron.
Which isotope of hydrogen is used commonly as a trace in organic chemistry?
Deuterium . Deuterium is an istope of hydrogen because it contains 1 proton, 1 neutron and one electron. The commonest isotope is protium , which contains 1 proton and one electrons, and NO neutrons. Deuterium has the atomic mass of '2'. Symbollically it is shown as [2/1]H . It has the ato,mic mass of '2' because the nucleus contains 1 proton and 1 neutron ; 1 + 1 = 2 Because of this extra 'maSS' it is sensitive to nmr . (nuclear magnetic resosnsnce), and hence it can be 'seen' on nmr spectra.
What is relative atomic number?
The relative atomic mass is defined as: "The weighted mean of the relative isotopic masses of an element on the scale where 12C is 12 amu exactly; symbol Ar." (Heinemann Chemistry 1, 4th Edition).An atomic mass is always near to the number of Protons and Neutrons within an atom. (12C has a relative atomic mass of exactly 12 amu, but 13C has a relative atomic mass of 13.003 amu for example). Isotopes are Atoms with the same number of protons but different numbers of neutrons. Isotopes used in the calculation of relative atomic mass are naturally formed. The percentage of each type of isotope within a sample of an element is calculated (one way is by using a mass spectrometer). The values are then used to calculate the relative atomic mass.Example: Calculating hydrogen's relative atomic mass Hydrogen has 3 common isotopes that are naturally formed. 1H (protium), 2H (deuterium), and 3H (tritium). The atomic masses and the percentage of each of these found in a sample is found to be: Atomic Mass % in sample (values may not be exact)1H 1.008 amu 99.986%2H 2.014 amu 0.014%3H 3.016 amu 0.0001%These are then used to calculate the relative atomic mass as follows ((1.008 amu * 99.986%) + (2.014 amu * 0.014%) + (3.016 amu * 0.0001%)) / 100% Which equals approximately 1.008143856 amu.
What element has three isotopes have different names?
Hydrogen has three isotopes with different names: protium (1H), deuterium (2H), and tritium (3H). Each isotope has a different number of neutrons in its nucleus.
How many neutrons are in an atom of deuterium 2H?
Deuterium, 2H has one neutron.
What are the forms of hydrogen?
There are three forms of Hydrogen (these are known as isotopes). These are normal hydrogen, deuterium and tritium.
What is the name given to 2H?
2H is called deuterium, which is an isotope of hydrogen. It is commonly used in nuclear reactions and in certain types of nuclear magnetic resonance spectroscopy.
Is H2 is it same as deuterium?
Having only one proton deuterium has the atomic number 1, as hydrogen; but because deuterium has also and a neutron, the atom is different compared to the atom of hydrogen. Consequently deuterium is an isotope of hydrogen with the Atomic Mass 2.
What are the names of the of the unstable hydrogen isotopes?
The only UN-stable Hydrogen isotope is Tritium, atomic number 1 (of coarse!), mass number 3, with 2 neutrons in nucleus, beta- electron emitter, (max.) 0.018 MeV, half-time 12.3 yr.
What is the difference between H2 and H1 isotopes?
They have different numbers of neutrons and therefore different atomic masses. Hydrogen-2, with 1 protons and 1 neutron has an atomic mass of 2. Hydrogen-1, with 1 proton and no neutrons has an atomic mass of 1. (By the way, the accepted way of writing these symbolically if you can't use subscripts is to put the number first, vis: 2H)
How cant you tell isotopes of the same element apart?
You can tell isotopes apart by the difference in there atomic mass numbers. Take for example the isotope Carbon-12. Carbon is the element name and 12 is the atomic mass of the element. The atomic mass number can (most?) always be changed, but the the atomic number ( the number above the Element symbol on the Periodic Table) cannot. Remember: The number of protons add by the number of neutrons equals the atomic mass number. The proton number = the atomic number, as of the number of electrons= the atomic number; hence the atomic number= number of proton = number of electron.
How do you write the notations for the three forms or isotopes of hydrogen?
Deuterium is written 4 H 1 I'm not sure how to type superscript and subscript but the top number is the atomic weight and the bottom # is the atomic number or the amount of protons
What does the chemical symbol 2H mean?
H2 is a hydrogen molecule made of two hydrogen atoms bonded together. The preceding two refers to the number of moles of H2 molecules in the chemical equation.
Which isotope of hydrogen is used commonly as a trace in organic chemistry?
Deuterium . Deuterium is an istope of hydrogen because it contains 1 proton, 1 neutron and one electron. The commonest isotope is protium , which contains 1 proton and one electrons, and NO neutrons.

What are three isotopes of H?
The main difference between the three isotopes of Hydrogen are the number of neutrons in the nucleus. Hydrogen has no neutrons, Deuterium has one neutron and Tritium has two neutrons. All three have one proton and one electrons.
Which symbol represents isotope of the symbol D?
D is deuterium, or 2H. An isotope of hydrogen with a neutron in addition to the proton.
