The Atomic Mass tells how much amu one atom of an element weighs. It, minus the atomic number, rounded to the nearest one, gives you the number of neutrons in an atom. The atomic number is the number of electrons and protons. Protons have a positive charge, electrons have a negative charge, and neutrons are neutral.

Actually, its the mass of 1 mole of an element (a mole being 6.02x10^23 atoms)
So 6.02x10^23 hydrogen atoms= 1 gram

If the atomic mass of an element is x what is the mass in grams of 6.021023 atoms of the element?
6.021023x
Why does not atomic mass of element represent the actual mass of the atoms?
Because the gram atomic mass of an element is the mass in grams of Avogadro's Number of atoms. To find the actual mass of a single atom, the gram atomic mass must therefore be divided by 6.022 X 1023.
Are all sample of elements are composed of atoms with same atomic mass?
All atoms in a pure sample of one element have the same mass. The atoms in a different element have a different mass. Different atoms is what makes different elements.
Can the atomic mass of individual atoms of an element vary?
No, the atomic mass of individual atoms of an element does not vary. The atomic mass listed on the periodic table is an average value that takes into account the different isotopes (atoms with different numbers of neutrons) of the element and their abundance in nature. Individual atoms of the same element will have the same atomic mass.
Does an isotope of an element have a different atomic mass?
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
How many atoms are in an element whose mass is equal to the atomic mass?
1
What does an element's atomic mass tell about the atoms that make up that element?
Atomic Mass is the no. of protons+no. of nuetron
How are atomic number and atomic mass alike?
Atomic number and atomic mass are not alike. Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Atomic mass is the combined masses of the protons, neutrons, and electrons of the atoms of an element. Individual isotopes of an element have specific mass numbers, which are the sum of the protons and neutrons in the nuclei of the atoms of the isotope.
What tells you how many atoms of an element there are?
the atomic mass, which is the mass of its protons and neutrons and electrons together
What does an element's atomic mass tell us about the atoms that make up that element?
atomic mass is the no. of protons+no. of nuetron
If the atomic mass of an element is x what is the mass in grams of 6.021023 atoms of the element?
6.021023x
What does the atomic mass of an element tell?
The gram atomic weight or gram Atomic Mass of a chemical element is the mass in grams of Avogadro's number of atoms of the element with the isotopic proportions found in nature.
How are atomic mass and atomic number different?
Atomic number is the number of protons in the nuclei of the atoms of an element. Atomic number is unique to each element. Atomic Mass is the combined mass of the protons, neutrons, and electrons in an atom of an element.
The atomic mass of an atom is the?
The atomic mass of an atom is the mass of 6.011 X 10^23 atoms of that element.
What are atoms of an element have the same atomic number but a different atomic mass?
isotope
Why does not atomic mass of element represent the actual mass of the atoms?
Because the gram atomic mass of an element is the mass in grams of Avogadro's Number of atoms. To find the actual mass of a single atom, the gram atomic mass must therefore be divided by 6.022 X 1023.
Tells you the number of atoms in each element?
atomic mass is the answer
