What is the relationship btw atomic mass and atomic mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What elements atomic mass is 18.99?
Fluorine
Why is the atomic mass number not a whole number?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the mass of one mole of Al2O3 if aluminum has an atomic number of 13 and an atomic mass of 26.98 and oxygen has an atomic number of 8 and an atomic mass of 16.00?
The mass of one mile of a compound is found by adding up the atomic masses of each of the component elements. A mole of Al2O3 has mass of 2 × 26.98 + 3 × 16.00 = 101.96g
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
Is there a difference between mass and atomic mass when dealing with elements?
Generally the term "atomic mass" is used for isotopes. For elements is preferred now "atomic weight".
How atomic number better than atomic mass?
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
How were the elements in the periodic table arranged?
By Atomic Mass
How are chemicals related to atomic mass?
The molar mass of a compound is the sum of atomic weights of the contained elements in the molecule.The expression atomic weight is correct for elements; for isotopes is correct atomic mass.
What is the atomic mass of this elements?
Gold is a meta element. Atomic Mass of it is 197.
What did Mendeleev think of the properties of the elements depended of?
Atomic Mass.
What Iron elements atomic mass?
Iron is a metal element. Atomic mass of it is 55.84.
What is the sum of atomic mass?
I suppose that you think to atomic weights (not mass) of chemical elements and the molecular mass.
In what order did Mendeleev arrange the elements in the first periodic table?
Mendeleev arranged the elements in the periodic table according to their atomic masses.
Is the atomic radius the same as the atomic mass?
No, the atomic radius and atomic mass are not the same. The atomic radius refers to the size of an atom, typically measured as the distance from the nucleus to the outer electron cloud. On the other hand, atomic mass is the mass of an atom, which is the sum of the protons and neutrons in the nucleus.
Did Mendeleev organize the elements by atomic mass or atomic number?
Mendeleev organized the elements by atomic mass. It was later discovered that organizing them by atomic number created a more accurate and logical periodic table.
What 2 elements have the closest atomic mass?
The two elements with the closest atomic mass are Bromine (atomic mass 79.9 amu) and Krypton (atomic mass 83.8 amu). They have a difference of only 3.9 atomic mass units.
