What is the weight of an atom?

Question

What is the weight of an atom?

Answer 1

You have to look it up on the periodic table.  The little number in the box is the mass of the atom in atomic mass units.

Answer 2

Which atom? They're all different depending on number of protons/neutrons.

Answer 3

The weight of an atom:

weight = m x g

or       = "the atom's mass" x 9.8m/s^2

For the hydrogen atom:

m=9.104 x 10^-31 kg

so, its weight = 9.104 x 10^-31 kg x 9.8 = 8.922E-30N

or, 2.00E-30 pound!

Answer 4

1.66E-24 gram for a hydrogen (protium) atom.

Multiply this value by the atomic mass of other element/isotope to get a rough estimate of their mass.

Answer 5

depends - i think hydrogen is like 1amu - different atoms have different weights!  (im like an 8th grader - u should soo kno this!)
