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.
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.
Which element has atomic number 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 are the isotopes of hydrogen atom?
Normal hydrogen (atomic weight 1), deuterium (2), and tritium (3).
When two atoms have the same number of protons but a different number of neutrons what are these atoms?
They are isotopes of each other.
What is the atomic number and mass number of deuterium 2H?
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 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 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.
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 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.
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.

Which element has atomic number 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 average atomic mass of hydrogen calculated?
One takes into account the percentage and atomic masses of protium and deuterium.
What is a example of a non atomic number?
Mass number is the sum of neutrons and protons. It is equals to total of their weights. As an example hidrogen-2 (deuterium) has a mass number of 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.
