Deuteriums emision spectrum either is like hydrogen http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch6/bohr.html or like http://en.wikipedia.org/wiki/Image:Deuterium_lamp_1.png

What is the atomic number for deuterium?

Deuterium is just an isotope of hydrogen, so the atomic number is 1.


What is the mass number and atomic number of deuterium and tritium?

Deuterium: atomic number 1, mass number 2Tritium: atomic number 1, mass number 3


What is the atomic number and mass number of deuterium 2H?

The atomic number is 1 and the mass number is 2.


What is the atomic mass and atomic number of Deuterium and Tritium?

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.


Why is deuterium an isotope?

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 is nuclear notation?

If you think to the notation of an isotope, see an example with deuterium: 21H - where 2 is the mass number of deuterium and 1 is the atomic number.


What is a form of a element that has the same atomic number but a different mass number?

It is an isotope, an example is hydrogen and deuterium.


Is deuterium an isotope?

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 is the relationship between istotopes mas number and neutrons?

atomic mass of an atom = number of neutrons + number of protons For example the Deuterium isotope of Hydrogen Atomic mass number = 2 Atomic number = 1 The atomic number is the same as number of protons, so the Deuterium isotope has 1 proton atomic mass of an atom = number of neutrons + number of protons 2 = n + 1 n = 1


what is deuterium atomic mass is?

Mass of deuterium is 2 amu (as it has 1 proton and 1 neutron).


Is The atomic number is always equal to the atomic weight?

No.The atomic number is dependent on the number of protons. The atomic weight is dependent on the number of protons and neutrons. As almost every element has some neutrons in its nucleus the atomic number will never be equal to the atomic weight.The one possible exception is Hydrogen with a single proton. However there are two isotopes of hydrogen: deuterium and tritium. Deuterium has one proton and one neutron. Tritium has one proton and two neutrons. Therefore when taken as a whole the atomic weight of hydrogen will always be slightly greater than 1g/mole.


Atomic mass unit of 2 deuterium?

2


Number of neutrons in deuterium?

There is 1 neutron in an atom of deuterium.


What element has a mass number of 2?

Deuterium, an isotope of hydrogen, has an atomic mass of 2 since it has a neutron as well as a proton in the nucleas. Hydrogen oxide, H20 is known as water - deuterium oxide is known as heavy water.


What is the mass number of deuterium?

Deuterium is an isotope of hydrogen, it has twice the mass of a hydrogen atom. A hydrogen atom's mass number is 1 so a deuterium atom would have a mass number of 2


The atomic number is determined by the number of?

This is determined by the number of protons in a atom. e.g. carbon has an atomic number of 6 because it has 6 protons.Neutrons are irrelevant to atomic number. For instance:Hydrogen has 1 proton, NO neutrons and has atomic number 1, its isotope Deuterium has 1 proton, ONE neutron and also has atomic number 1.


What is the average atomic mass of hydrogen calculated?

One takes into account the percentage and atomic masses of protium and deuterium.


Why Helium with equal number of protons and neutrons is stable but Deuterium does not?

On the contrary, deuterium is stable.


How do you know that a deuterium is a form of hydrogen not a form of helium?

Deuterium has 1 proton, and therefore an isotope of Hydrogen. Remember the number of protons is what changes the atomic number, and what element a atom is. When tritium and deuterium react under immense pressure and heat they form Helium (and omits a neutron) This is the most basic example of nuclear fusion.


What is the mass number for deuterium?

237


The mass number of deuterium?

2


What atom has an atomic mass of 3?

Deuterium, which is an isotope of hydrogen, has an atomic mass of 3. It has one proton and two neutrons in its nucleus.


What is the mass number of deterium?

The mass number of deuterium is 2


How many isotopes in hydrogen?

Isotopes of an element have the ssame number of protons (and therefore, atomic number), but different numbers of neutrons (and therefore, atomic masses). Isotopes are abbreviated by the atomic mass followed by the atomic symbol. Three isotopes of hydrogen exist: hydrogen, 1-H; deuterium, 2-H; and tritium, 3-H. Each of these isotopes has one proton (which gives them and atomic number of 1: hydrogen), and they have 0, 1, or 2 neutrons, respectively.


What is that atomic number of an element?

The atomic number indicates the number of protons in a given element. It also helps with calculating the weight number to determine if the material in question is an isotope or not (e.g. even though deuterium and tritium are basically isotopes of hydrogen, they may work differently and definitely weigh differently than plain ol' hydrogen).
