The Atomic Mass of an element represents the average mass of an atom of that element, taking into account the abundance of different isotopes of the element. It is measured in atomic mass units (amu) and is listed on the Periodic Table below the element's symbol.
What else can I help you with?
When does the atomic mass of an element represent?
The average total mass of its neutrons,protons and electrons
What does atomic mass represent of an element represent?
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
What does the number after the element represent eg carbon-14?
It represents the mass number of that particular isotope.
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.
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.
Why is atomic structure so difficult to determine?
You only use the average atoimc weight with isotopes correct? One of the problems on MasteringChemistry asked what is the average atoimc mass of element X and gave four isotopes. I guess I was confused because I used the formula for average atoimc weight and got it wrong. Can we do one of those in lecture?
What does the atomic mass represent for manganese?
Manganese is a meta element. Atomic mass of it is 25.
When does the atomic mass of an element represent?
The average total mass of its neutrons,protons and electrons
What does the decimal number in an element key represent?
atomic mass
What does the atomical number represent?
The Atomic Mass is the mass (weight) of the element measured in atomic mass units (AMU)
What does atomic mass represent of an element represent?
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
Why does not an atom of an element represent the actual mass of its atom?
An atom of an element does not represent the actual mass of its atom because the atomic mass listed on the periodic table is an average mass calculated based on the relative abundance of different isotopes of the element. Isotopes are atoms of the same element with differing numbers of neutrons, so the actual mass of an atom of a specific isotope may vary slightly from the average atomic mass.
What does the mass of an element represent?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
Can you tell which element represent by Hf?
an element of period 6 name has hafnium having atomic no 72 and atomic mass as 178.49
What does the number after the element represent eg carbon-14?
It represents the mass number of that particular isotope.
