Yes. There's even a stable atom with an Atomic Mass of 200 (well, not QUITE 200): Mercury has a stable isotope with a mass of 199.9683. Several other elements (platinum, gold, lead, etc.) have isotopes with atomic mass near 200, but they're all radioactive.
No, an atom of aluminum and an atom of gallium do not have the same atomic mass. Aluminum has an atomic mass of approximately 26.98 atomic mass units, while gallium has an atomic mass of approximately 69.72 atomic mass units.
Atomic mass
The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
The atomic mass of an oxygen atom depends on which isotope of oxygen you are referring to. The AVERAGE atomic mass is approximately 15.9994
In one atom of mercury with a mass number of 200, there are 120 neutrons (mass number - atomic number = number of neutrons).
No, an atom of aluminum and an atom of gallium do not have the same atomic mass. Aluminum has an atomic mass of approximately 26.98 atomic mass units, while gallium has an atomic mass of approximately 69.72 atomic mass units.
Mercury has an atomic mass of 200.
Proton + Nuetron = Atomic Mass
Mercury is a non metal element. Atomic mass of it is 200.59.
The atomic mass of an atom is the combined mass of the protons and neutrons in the nucleus.
Atomic mass
The number of neutrons in an atom can affect the atomic mass of an atom.
The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
The atomic mass of an atom is the mass of 6.011 X 10^23 atoms of that element.
The atomic mass of an oxygen atom depends on which isotope of oxygen you are referring to. The AVERAGE atomic mass is approximately 15.9994
