What else can I help you with?
By using the periodic table how did you determine how many neutrons are the most common isotope of an element?
Usually the periodic table would not be a good source to determine the number of neutrons; the periodic table focuses on the atomic number, which is the number of protons. An element with a given number of protons can have multiple isotopes, which are elements with the same number of protons but a different number of neutrons; in some cases there are a rather large variety of isotopes. Having said that, some periodic tables do represent the commonest isotope or commonest naturally occurring one but are still unlikely to list all possible isotopes.
Could you use average number of neutrons instead of atomic number to build up a periodic table good as that of mendeleyev?
it won't be possible since some elements exixts as isotopes
Why does the atomic mass on the periodic table progressively changes left to right and top to bottom why?
Because there are increasingly more protons, electrons, and neutrons. Atomic mass is the average number of neutrons in all of the isotopes(different types) of a specific element, meaning you can sometimes have decimal masses. But, the atomic number is never a decimal because the atomic number is just a numbering system for all the elements.
Why is atomic mass for an element an average on the periodic table?
The atomic mass is an average because most atoms have isotopes sometimes up to 10 or more. These all have different numbers of neutrons and subsiquently different weights. For this reason an average of these weights needs to be used for the atomic mass.
What three facts about the elements can be derived from the periodic table?
You can find out what groups certain elements are in, and find there relative atomic masses. You can also find outy how reacticve they aRE AND HOW MANY ELECTRONS NEUTRONS AND PROTONS ARE IN CERTAIN ELEMENTS

Which number is the atomic mass?
The atomic mass of an element is average of the number of protons in an atom plus the number of neutrons. For example, if you look at a periodic table of elements, Hydroge has the atomic mass of 1.0079.
Do the elements in a row on the periodic table have the same average atomic mass?
no.

How do you determine the numbers of subatomic particles in an atom based on its identity?
The number of protons in the nucleus determines the atom's identity. This is the atomic number on the periodic table. The number of electrons in a neutral atom is equal to the number of protons. Neutrons can vary, but the atomic mass on the periodic table provides an average number of protons and neutrons in an atom.
What is the isotope number used for on the periodic table?
There is not an isotope number on the Periodic Table of Elements. There is an atomic number (# of protons) and the average atomic mass. The average atomic mass is the weighted average of all the naturally occurring isotopes for each element. This number is not a whole number, because it is an average of all the isotopes for a particular element.
Why does the mass number not appear on the periodic table?
Mass number is a property specific to a particular isotope or nuclide of an element, while the usual periodic table include average properties for all the stable, naturally occurring isotopes of each element.
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
What is the logic to write the position of an element in periodic table?
The Periodic Table's layout arranges all of the known elements in periods according to things such as the number of electrons in the outer shell, the type of element (i.e. alkali metal or alkali earth metal) etc. The elements also go along in increasing numbers of atomic number, which is the number of protons and neutrons in the average atom of each element.
