Atomic mass is also known as atomic weight. Atomic mass is the weighted average mass of an atom of an element based on the relative natural abundance of that element's isotopes. The mass number is a count of the total number of protons and neutrons in an atom's nucleus.

Is the atomic mass of an element its actual mass?
No, it is not the actual mass of the element. It is its actual mass relative to a reference standard.
Why does atomic mass of an element is not considered as the actual mass of its atom?
Atomic Mass : It is the total mass of protons and neutrons in an individual atom or isotope. Since, Atomic Mass is total mass of protons and neutrons in an individual atom or isotope and not the actual weight of an Atom.
Is atomic mass same for all elements or is it different for different atoms explain?
The atomic mass " is simply the total number of nuclear particles (protons + neutrons). Mostly it is different in different atoms but it is same in few cases, elements which have different atomic number but have same atomic mass are known as isobars.
What is actual mass of an atom?
The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.
How do we calculate atomic mass?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
What is atomic mass example?
An atomic mass unit is defined as a mass equal to one twelfth the mass of an atom of carbon-12. The mass of any isotope of any element is expressed in relation to the carbon-12 standard. For example, one atom of helium-4 has a mass of 4.0026 amu. An atom of sulfur-32 has a mass of 31.972 amu.
Why is the mass number of an atom?
The mass number of an atom is its total number of protons and neutrons. Atoms of different elements usually have different mass numbers , but they can be the same. For example, the mass number of argon atoms and calcium atoms can both be 40.
Do all atoms of a particular element have the same mass?
Atoms of the same chemical element do not always have the same mass because, although the number of protons in the nucleus is the same for all atoms of the same element, the number of neutrons is not. Most elements as they occur naturally on earth are mixtures of several isotopes.
Why can't you see an atom with the naked eye?
Answer: It is not possible to see an atom with naked eye because of its extremely small size (atomic radius is of the order of 10-10 m).
