Why do the mass of atom depend upon the nucleus?
The mass of an atom depends on the nucleus because the nucleus contains the majority of the atom's mass in the form of protons and neutrons. Electrons, which orbit the nucleus, have a much smaller mass compared to protons and neutrons. The mass of an atom is essentially the combined mass of its protons and neutrons in the nucleus.
Does the average mass of an atom depend on the source of that atom?
Yes. An atom of He will be twice that of H because it has twice as many neucleic particles (a proton and neutron vs a proton) There really isn't an average mass of an atom. You can look up the masses of atoms though, on the Periodic table of Elements
Is an oxygen atom have twice the mass of a sulphur atom?
No, an oxygen atom does not have twice the mass of a sulfur atom. An oxygen atom has a mass of approximately 16 atomic mass units (amu), while a sulfur atom has a mass of approximately 32 amu. Therefore, a sulfur atom has twice the mass of an oxygen atom.
The average mass of a boron atom is 10.81 Assuming you were able to isolate only one boron atom the chance that you would randomly get one with a mass of 10.81 is?
The chance of isolating a boron atom with a mass of exactly 10.81 is very low since the average mass accounts for various isotopes of boron that have different masses. The probability would depend on the abundance of each isotope in nature.
The relative atomic mass of an atom can be found by comparing the mass of the atom to the mass of?
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.
What represents most of an atom's mass?
The nucleus of an atom represents most of an atom's mass.
In 4gm of Ag .calculate weight of one atom of Ag?
That should be mass, not weight. The mass of one atom of Ag doesn't depend on the size of the sample. Also, you can't "calculate" the mass of one atom from the information provided. You can look it up - or you can look up the atomic mass of Ag, and multiply it by the atomic mass unit.
What does adding A neutron to an atom's do to the atom's mass?
Adding a neutron increases the atom's mass by about 1 AMU assuming it remains stable.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
Is the mass of an iron atom any different from the mass of a copper atom?
Yes, the mass of an iron atom is different from the mass of a copper atom. The mass of an iron atom is approximately 56 atomic mass units, while the mass of a copper atom is approximately 63.5 atomic mass units. Therefore, there is a difference of about 7.5 atomic mass units between the two.
Where is he mass of an atom concentrated?
99.9% of the mass of an atom is located in the nucleus
