The Atomic Mass of an element depends on the weight of the protons, neutrons, and electrons (almost negligible) in one mole (6.022 x 10^23 atoms) of the element.
What else can I help you with?
What 2 parts of an atom have the same mass?
Proton and neutron have similar mass, but not identical.
What is 1 proton 2 neutrons?
<P>proton + neutrons give you a nucleon. the nuceon(or protons +neutron) give you the overall mass of the atom. the mass of electrons is not included, i dont even think that it has mass at all. Hope you're answered?</P>
What is the mass of a radium atom?
The atomic mass of a radium atom is approximately 226. It is a highly radioactive element found in group 2 of the periodic table.
What is the mass number of a helium atom that has 2 protons and 2 neutrons?
Number of neutrons = Mass number - Number of protons = 4 - 2 = 2 neutrons
This atom is a of helium -4?
The atom is an isotope of helium called helium-4. It contains 2 protons and 2 neutrons in its nucleus, giving it a total atomic mass of 4 atomic mass units.
What 2 parts of an atom have the same mass?
Proton and neutron have similar mass, but not identical.
Which 2 parts in an atom have the same mass?
Protons and neutrons have approximately the same mass in an atom. Protons have a mass of about 1 atomic mass unit (amu), while neutrons have a slightly larger mass of about 1 amu.
What is the mass number of this atom?
2

If a hydrogen atom has a mass of 3 is it an isotope?
No, a hydrogen atom with a mass of 3 is not an isotope of hydrogen. Hydrogen isotopes include protium (mass 1), deuterium (mass 2), and tritium (mass 3).
What is the total mass of an atom having 2 neutrons 2 electrons and 2 protons?
It is about the helium gas. mass number of it is 4.
What is the mass of a radium atom?
The atomic mass of a radium atom is approximately 226. It is a highly radioactive element found in group 2 of the periodic table.
What percentage of an atom's mass is caused by the Higgs boson?
About 2% of an atom's mass is caused by the Higgs boson. The rest is due to the effect of the Strong Nuclear Force.
How many protons does an atom of Carbon have if it has a plus 2 charge and a mass of 15?
An atom of Carbon with a mass of 15 and a +2 charge must have 13 protons. This is because the atomic number of Carbon is 6, so a neutral Carbon atom would have 6 protons. Since the atom has a +2 charge, it has lost two electrons, making it a cation, and giving it 2 more protons than electrons.
What is the mass number of a helium atom that has 2 protons and 2 neutrons?
Number of neutrons = Mass number - Number of protons = 4 - 2 = 2 neutrons
This atom is a of helium -4?
The atom is an isotope of helium called helium-4. It contains 2 protons and 2 neutrons in its nucleus, giving it a total atomic mass of 4 atomic mass units.
What is the mass number of helium atom?
The atomic number of helium is 2. Its mass is 4.002602 u ± 0.000002 u
