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.
What else can I help you with?
What does the atomic mass represent for manganese?
Manganese is a meta element. Atomic mass of it is 25.
What does the atomical number represent?
The Atomic Mass is the mass (weight) of the element measured in atomic mass units (AMU)
What does the decimal number in an element key represent?
atomic mass
What does atomic mass represent of an element represent?
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
When does the atomic mass of an element represent?
The average total mass of its neutrons,protons and electrons
What does the atoimc mass of an element represent?
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.
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
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 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 do the numbers and letters in the periodic table represent?
either mass or protons the top is the atomic number it shows how many protons the bottom number is the atomic mass also the weight
What is the atomic mass for magnesiam?
Magnesium is a meta element. Atomic mass of it is 24.
Which element has the atomic mass of 126.9045?
The element is Iodine (I). It has an atomic mass of about 126.9.
