What is the difference between the periodic table and Mendeleev's table?
Mendeleev's table was arranged by atomic mass and the periodic table is arranged by protons (atomic number).
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 did mendeleev's ordering actually correspond to?
Atomic mass. The modern table is based on atomic number.
Why was mendeleev's periodic table valid at all?
His table was sorted by atomic mass, not atomic number. (the way today's periodic table is sorted) Mendeleev was almost right, but they did not know about protons at the time. (atomic number is the number of protons in an element) There would have been absolutely no way of him figuring out they were related to atomic number if he didn't even know about atomic number
What particle contributes to the atomic number?
Number of protons are taken. They are arranged by number of protons. Mendeleev arranged elements first according to atomic number
What is the atomic number and how is it used to distiguinsh?
The atomic number is equal to the number of protons in an atomic nucleus; the atomic number is the order number of a chemical element in the periodic table of Mendeleev.
What is the difference between the periodic table and Mendeleev's table?
Mendeleev's table was arranged by atomic mass and the periodic table is arranged by protons (atomic number).
Who arranged the periodic table in accordance to atomic number?
Mendeleev
Which was NOT used by Mendeleev to organize his periodic table?
Atomic Number
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 do you mean by atomic number?
Atomic number = Number of protons = Number of electrons (in the neutral state) Also the atomic number is number of a chemical element in the periodic table of Mendeleev.
Mendeleev arranged the elements in his periodic table in order of?
Mendeleev arranged the elements by increasing atomic mass instead of like today by increasing atomic number.
What did mendeleev's ordering actually correspond to?
Atomic mass. The modern table is based on atomic number.
What do the numbers on mendeleev's periodic table represent?
The Atomic number which is the number of protons in an atom's nucleus.
What contributes to the atomic number?
Number of protons are taken. They are arranged by number of protons. Mendeleev arranged elements first according to atomic number
An element atomic number is the what?
Atomic number = number of protons = number of electrons (in the neutral state) Also the atomic number is the number of the position of a chemical element in the periodic table of Mendeleev.
Who presented the periodic table according to atomic number?
Dmitri Mendeleev
