No. I would expect each atom of any particular compound to have similar but not the same mass. This is because, although each atom will have the same number of protons and electrons, they can have different numbers of neutrons. The mass of an atom is almost entirely dependent on the number of protons and neutrons.
Tin, for example, has atomic number 50 so that it has 50 protons and 50 electrons. But is has 10 stable isotopes:
- Sn 112 - with 62 neutrons
- Sn 114 - with 64 neutrons
- Sn 115 - with 65 neutrons
- Sn 116 - with 66 neutrons
- Sn 117 - with 67 neutrons
- Sn 118 - with 68 neutrons
- Sn 119 - with 69 neutrons
- Sn 120 - with 70 neutrons
- Sn 122 - with 72 neutrons
- Sn 124 - with 74 neutrons
In addition, there are 29 known non-stable isotopes, including Sn 126 which has a half-life of approx a quarter of a million years.
Six of the stable isotopes have an abundance of 5% or more so it is quite likely that atoms of tin have different masses.

Which would have more of an affect on the mass of an aluminum atom removing ten electrons or one neutron?
Removing ten electrons would have a larger effect on the mass of an aluminum atom than removing one neutron. Electrons have very little mass compared to protons and neutrons, so removing ten electrons would significantly decrease the mass of the atom. Neutrons contribute roughly the same mass as protons, so removing one neutron would have a smaller impact on the overall mass of the atom.
If a sodium atom has 11 protons and 12 neutrons what is its mass number?
The mass number of an atom is the sum of its protons and neutrons. In this case, the mass number of the sodium atom with 11 protons and 12 neutrons would be 23.
What is mass number equal to?
The mass number of an atom is defined as the total number of protons and neutron (collectively called "nucleons") in the atomic nucleus. For example, a helium atom with 2 protons and 2 neutrons would have a mass number of 4.
The mass number of an atom of calcium with 20 protons and 20 neutrons is?
The mass number of an atom is the sum of the protons and neutrons in its nucleus. Therefore, for an atom of calcium with 20 protons and 20 neutrons, the mass number would be 40.
What is the mass of calcium atom compared with the mass of helium atom?
The mass of a calcium atom is around 40 atomic mass units (u), while the mass of a helium atom is around 4 atomic mass units (u). Therefore, the mass of a calcium atom is 10 times greater than the mass of a helium atom.
Will kilogram of hydrogen contain more atoms then kilogram of lead?
Yes, because each hydrogen atom has less mass than each lead atom.Yes, because each hydrogen atom has less mass than each lead atom.Yes, because each hydrogen atom has less mass than each lead atom.Yes, because each hydrogen atom has less mass than each lead atom.
Is all of the mass in an atom in the nucleas?
The mass of an atom is mostly in the nucleus. Though electrons that orbit the nucleus also have mass, their masses are so small (each electron is 1/1823th the mass of a proton), the mass of any atom would be 99.9% in the nucleus.
What is the Mass of an atom is located in what structure of the atom?
In the nucleus of the atom, protons and neutrons therein each add 1 atomic mass unit.
Do subscripts represent the relative mass of each type of atom in the compound?
No, subscripts in a chemical formula represent the number of atoms of each element in the compound. The relative mass of each atom is accounted for by the atomic mass of the element found in the periodic table. So, atomic mass, not subscripts, gives you the relative mass of each type of atom in a compound.
How many mass units is there if each atom of element X has 13 mass units and each atom of element Z has 31 mass units?
The answer depends on how many atoms of X and Z are found in each molecule of the compound.
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.
What is the mass in grams of a single atom of each of Ne?
The atomic mass of Ne (neon) in grams is approximately 20.180 grams per mole. This means that a single Ne atom would have a mass of about 3.35 x 10^-23 grams.
How do you calculate the atomic mas based on the number of protons and neutrons of an atom?
To calculate the atomic mass of an atom, you would add the number of protons and neutrons together. Protons and neutrons each have a mass of approximately 1 atomic mass unit (amu). The sum of the protons and neutrons will give you the atomic mass of the atom in atomic mass units.
What is the atomic mass of an atom if its mass is approximately one third that of carbon 12?
The atomic mass number of an atom, if the atom's mass number is approximately equal to 0.33 that of carbon-12, would be 4. If the question is about actual masses rather than mass numbers, the mass of a helium-4 atom is about 4.00260 atomic mass units, while the mass of a carbon-12 atom is, by definition, exactly 12.000..... atomic mass units.
Do the elements in the periodic table have the same mass?
No! The mass of one atom of each element increases as you move down and to the right on a periodic table. The mass of an atom of a particular element is called its atomic mass.
What is the atomic mass of this atom 19p and 20n?
To calculate the atomic mass of an atom, you would add the number of protons and neutrons together. In this case, the atom has 19 protons and 20 neutrons, totaling 39 nucleons. The atomic mass of this atom would be approximately 39 atomic mass units (amu).
What is an atomis mass?
Atomic mass is the mass of an atom, typically expressed in atomic mass units (amu). It is a weighted average of the mass of an atom's isotopes, taking into account their relative abundance in nature. It is usually found on the periodic table beneath the chemical symbol of each element.
