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
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.
Did Mendeleev organize the elements by atomic mass or atomic number?
Mendeleev arranged elements in order of increasing mass. Later modern periodic table was discovered that contains elements arranged by atomic number.
Elements were originally placed in order of atomic now they are placed in order of atomic?
Elements were originally placed in order of atomic massnow they are placed in order of atomic number
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.
Did Mendeleev organize the elements by atomic mass or atomic number?
Mendeleev arranged elements in order of increasing mass. Later modern periodic table was discovered that contains elements arranged by atomic number.
The atomic mass of iodine is less than the atomic mass?
The atomic mass of iodine is less than the atomic mass of all elements with greater atomic number.
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.
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.
