Deuterium is just an isotope of hydrogen, so the atomic number is 1.
Deuterium: atomic number 1, mass number 2Tritium: atomic number 1, mass number 3
The atomic number is 1 and the mass number is 2.
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.
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.
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.
It is an isotope, an example is hydrogen and 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.
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
Mass of deuterium is 2 amu (as it has 1 proton and 1 neutron).
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.
There is 1 neutron in an atom of deuterium.
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.
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
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.
One takes into account the percentage and atomic masses of protium and deuterium.
On the contrary, deuterium is stable.
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.
Deuterium, which is an isotope of hydrogen, has an atomic mass of 3. It has one proton and two neutrons in its nucleus.
The mass number of deuterium is 2
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.
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).
