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 does atomic mass number elements symbol elements name and atomic mass tell you about the element?
The element symbol represents one mole of element , atomic number represents number of protons, atomic mass represents sum of protons and neutrons.
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 average atomic mass represent?
The average Atomic Mass represents the weighted average of the masses of the isotopes of the element.
What is the atomic mass for magnesiam?
Magnesium is a meta element. Atomic mass of it is 24.
What number on the periodic table represents the mass in grams of one Mole of atoms in an element?
The atomic weight
What does atomic mass number elements symbol elements name and atomic mass tell you about the element?
The element symbol represents one mole of element , atomic number represents number of protons, atomic mass represents sum of protons and neutrons.
What does atomic mass represent of an element represent?
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
What is the same as the atomic mass number of an element?
Atoms atomic number represents their number of protons.
What does the periodic number tell you about the element in the period?
The atomic number represents the number of protons. The atomic mass represents the number of protons + neutrons.
What does the average atomic mass represent?
The average Atomic Mass represents the weighted average of the masses of the isotopes of the element.
What information could you use to determine the atomic number of an unknown element that has a mass number of 22?
the only element with a mass number of 22 is sodium (Na) which has an atomic number of 11. This is because the atomic number only represents the number of protons in the nucleus, while the mass number represents the number of protons and neutrons in the nucleus.
What is significance of the symbol of an element?
Sigificance of the Symbol of an Element :- 1. Symbol represents name of the element. 2. Symbol represents one atom of the element. 3. Symbol also represents one mole of atoms of the element. That is, symbol also represents 6.022 x 1023 atoms of the element. 4. Symbol represents a define mass of the element (equal to Atomic Mass expressed in grams).
What is the atomic mass for magnesiam?
Magnesium is a meta element. Atomic mass of it is 24.
What number on the periodic table represents the mass in grams of one Mole of atoms in an element?
The atomic weight
What is the number above the elements symbol?
the number above the symbol is the atomic....... of that element.
Which element has the atomic mass of 126.9045?
The element is Iodine (I). It has an atomic mass of about 126.9.
What is the difference between atomic size and atomic number?
The atomic number of an element determines the number of protons that are present in that element. The atomic size refers to the distance that the outermost valence electrons are from the nucleus.
