How are the atomic numbers and the atomic masses of the elements related to how the elements are arranged on peridoic table?
Elements are arranged in a periodic table by atomic number, lower on top and left. Atomic masses have no direct relationship to the arrangement of atoms, although generally atoms with higher atomic numbers will have higher atomic masses. (There are at least three exceptions for atoms with atomic numbers differing by 1.)
Where are the isotopes of the same elements having different atomic masses placed in the periodic table?
same slot
What are atoms of the same element thay have different atomic masses?
when you have two different forms of an atom with different masses, it's called an isotope of the atom.
Which term describes atoms with different atomic masses due to varying numbers of neutrons?
Isotopes (Pretty Sure)
Atoms of the same element with different atomic masses?
what is an atom of the same element with different mass numbers
Why don27t elements in the periodic table have whole numbers for their atomic masses?
Because the masses of protons, neutrons and electrons are not whole numbers.
Why the atomic mass numbers listed for elements on the Periodic Table are not whole numbers.?
Why are atomic masses of elements not generally whole numbers? The atomic masses listed on the periodic table are a weighted AVERAGE of an element'sisotopes. ... An element's atomic number is the number of protons in its nucleus. Number of protons specifies atom type.

(There are at least three exceptions for atoms with atomic numbers differing by 1.)
What does a periodic table have?
a modern periodic table should have the 118 elements, their atomic numbers, and their masses. to find the number of protons and electrons, they are the same as the atomic number. to find the neutrons, subtract the protons from the mass.
Why was basis of classification of element in the periodic table changed from atomic mass to atomic number?
Mendeleev's periodic table was based on the atomic masses of elements. However, this was not effective when isotopes were discovered. An isotope of an element is defined as the element having the same atomic number but varying mass numbers. So, mass numbers weren't constant and hence, a better characteristic was chosen -atomic number. Atomic number of any element was a characteristic of a particular element. Hence atomic numbers were taken as the basis of classification instead of atomic masses.
Define periodic law?
Properties of elements are a periodic function of their atomic masses.
How did Mendeleev arrange chemical elements?
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
Why do we need atoms?
According to modern Periodic Table Atomic numbers are the fundamentals in order to explain the properties of an atom.One thing more and that is the concept of isotopes also make the atomic masses less strong to explain atomic properties which has no effect on atomic numbers.
How do you learn atomic masses and atomic number?
You would either have to look them up in a periodic table, internet (eg. wikipedia) or in a manual, or you'd have to learn them by head, like you do with telephone numbers.
Is the mass and atomic mass the same?
No. The atomic weight is the number on the Periodic Table and is a weighted average of the atomic masses.
How were the atomic number and the atomic masses of the elements determined?
Atomic masses are determined by mass spectrometry. The atomic number is identic with the number of protons in the atom - depends on position in the periodic table.
What are the masses on the periodic table mostly not whole numbers?
1. First cause: the atomic weight is the sum of the weights of protons, neutrons ans electrons.; they don't have masses as integers. 2. Second cause: also occurs the so-called mass defect. Note: no atomic masses for elements but atomic weights is correct.
