Deuterium (D) is an isotope of hydrogen consisting of 1 neutron and 1 proton. Oxygen (O) has 8 neutrons and 8 protons in its most abundant isotope, 16O (99.7% of all oxygen). Therefore, D2O has 10 neutrons and 10 protons per molecule, 99.7% of the time.

∙ 8y agoD2O is a molecule and NOT an atom therefore it can NOT have an atomic weight.
The molar mass of D2O is 20.0276 g mol−1

∙ 10y agoThe sum of protons and neutrons in the atomic nucleus is called "mass number"; this value is different for each isotope.

What is the location of neutrons in the atoms?
Neutrons are located with Protons in the Nucleus.
Atoms consist of a nucleus containing?
Protons and neutrons ... which in turn contain quarks.
In atoms protons and neutrons are found where?
In the nucleus
What are located at an atoms nucleus?
Protons and neutrons are found in the nucleus.
What do all atoms of a element have in common?
The identity of an atom is defined by its Atomic Number, the number of Protons in the Nucleus. If the atom is un-ionized, it will also have the same number of electrons. So, just to be excruciatingly specific, every atom of the same element has exactly the same number of protons.
What type of information does the atomic number provide?
The total number of protons and neutrons in an atoms nucleus. The proton number on the other hand states just the number of protons in an atoms nucleus, hence the atomic number take away the proton number equals the number of neutrons in an atoms nucleus.
Do atoms have different amounts of protons neutrons and electrons?
An atom is comprised of a nucleus of protons and neutrons, and layers of 'shells' in which the electrons revolve around the nucleus. An element is defined by the number of protons in the nucleus while the number of electrons on the outer shell define an atoms group on the periodic table. Then the number of neutrons is added to the number of protons to define the atomic weight of the atom.
What identifies an atoms as being of the same element?
The number of protons and neutrons in the nucleus.
What is the number of protons in the nucleus of an atoms atomic?
The sum of protons and neutrons in the atomic nucleus is called "mass number"; this value is different for each isotope.
What is the location of neutrons in the atoms?
Neutrons are located with Protons in the Nucleus.
Atoms consist of a nucleus containing?
Protons and neutrons ... which in turn contain quarks.
Were were neutrons found in atoms?
In the nucleus, with the protons.
What does a atoms nucleus contain?
protons and neutrons
What does atoms nucleus contain?
protons and neutrons
In atoms protons and neutrons are found where?
In the nucleus
What are located at an atoms nucleus?
Protons and neutrons are found in the nucleus.
What is the atoms mass number?
The Atomic Mass number tells how many protons and neutrons are in a nucleus.
