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.
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
Mendeleev arranged the elements in his periodic table in order of?
Mendeleev arranged the elements in his periodic table in order of increasing atomic mass while also grouping elements with similar properties together. His periodic table laid the foundation for the modern periodic table we use today.
What is the atomic mass number of methane?
The atomic mass number of methane (CH4) is the sum of the atomic masses of its constituent elements. Carbon has an atomic mass of approximately 12, and hydrogen has an atomic mass of approximately 1. Adding these together gives a total atomic mass number of 16 for methane.
How would the modern periodic table would be different if elements were arranged by average atomic mass instead of by atomic number?
how would the modern Periodic Table be different if elements were arranged by average Atomic Mass instead of by 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.
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.
What 2 elements have the closest atomic mass?
the 2kg is closest to 2020g because it is the only number that can work for this answer.
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.
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.
