Not to a chemist, when they are both expressed in grams! For a physicist, "mass" is the preferred term because it is an inherent property of the material, whereas the weight will vary if an atom is in a different gravitational field than that of the Earth. In physics, "weight" is not expressed in simple "grams" but rather in "grams force".
What else can I help you with?
How is an atomic weight different than an atomic number?
atomic weight goes up faster
What has a heavier atomic weight gold or oxygen?
Gold has a heavier atomic weight than oxygen. Gold's atomic weight is approximately 197, while oxygen's atomic weight is around 16.
What has a different mass number than the normal atom?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
How is atomic weight different than an atomic number?

What is atomic mass and the number of calcium?
Calcium has atomic number of 20, an atomic weight of 40.078 and an mass numbers of 40 - 48 inclusive in its isotopes. Atomic number is the count of protons in the nucleus. Mass number is the count of protons plus neutrons. The question refers to atomic mass rather than atomic weight. Atomic mass normally refers to the mass of a specific isotope of an element and is related to the mass number. Atomic weight ( or relative atomic mass as it is termed by IUPAC) the average mass of naturally occurring isotopes of an element. The relationship between mass number and atomic mass is defined in terms of the Atomic mass unit which is in simple terms 1/12 of the mass of a 12C atom. If you need to find out more about the relationship between mass number and and atomic mass you need to read the article "atomic mass unit" in wikipedia.
Is it true that isotopes have the same atomic weight?
Atomic mass is the mass of an atom Atomic weight is the average mass of an atom based on the abundance of different isotopes No, because mass and weight are two different things. Weight is gravitational pull, while mass is how much matter there is in an object.
How heavy is the element Neon?
The atomic weight of neon is 20.180 amu, or atomic mass units.
What is the difference between atomic weight and atomic mass and molar mass and molecular weight?
The atomic mass is the mass of an atom at rest. This refers to one atom, and is typically measured in so-called atomic mass units, and describes a single isotope of that element. The atomic weight is the abundance-weighted average mass of an element (an average mass of all the isotopes that exist for that element, weighted by how abundant each isotope is in nature). Atomic weight is commonly reported in atomic mass units, as well as in grams per mole. The molar mass is the mass of one mole of something, and can refer to both a single element as well as molecules and other compounds. The molecular weight is essentially the same thing as the molar mass except that, as the name implies, it refers to molecules rather than just elements. The molar mass and molecular weight is typically given in units of grams per mole.The molecular weight of a compound is found by adding the atomic weights of all of the atoms in the compound. Water, for example, has a molecular weight of 18.0152 grams/mole, as there are two hydrogen atoms that each have an atomic weight of 1.00079 g/mole and one oxygen atom with an atomic weight 15.9994 grams/mole.
Does an oxygen atom weight the same as a hydrogen atom?
an oxygen and a hydrogen atom do not weight the same
What one has more mass an atom of gold or lead?
An atom of lead has more mass than an atom of gold. This is because lead has a greater atomic mass than gold, due to the larger number of protons, neutrons, and electrons in a lead atom compared to a gold atom.
Can an atom of two different elements have the same mass number?
Yes. The mass number is basic to the different elements, even more useful than the atomic number. (Unless it is an isotope. Isotopes have a different amount of neutrons than the basic element atom which makes a difference in mass number too. So, a difference in mass numbers doesn't always mean it is a different element.)
Number of atomic mass for element silver?
The atomic number for Silver (Ag) on the periodic table is 47. The average atomic weight is about 107.87, showing that silver normally has more neutrons than protons. (If all silver atoms had equal neutrons and protons, it would have an atomic weight of about 94).
