A. Electron
B. Proton
C. Neutron
D. None of these
Elements are placed in order on the periodic table based on their atomic number, how many protons they have. In a neutral atom, the number of electrons will equal the number of protons, so we can easily determine electron number from atomic number.

i think the electron would be the most appropriate atomic particle that should determine the position of an element on thr periodic table since we use the outermost electrons or valence electrons to determine the group of an element.
The appropriate answer should be Atomic Number as Atomic Number reflects number of Electrons or Protons of an atom. Since, in Periodic Table, all Elements are in atomic state, so atomic number should be the correct and appropriate answer.
Electron
The position of an element in Periodic Table is largely dependent on its ELECTRONS.
According to mosly the chemist scientist
He introduced modern periodic table according to the num of protons
It’s proton not electron
Because electron can be lost or gained by an atom
Dear. The correct answer is no of proton. The element are placed in periodic table according to increasing atomic no (after moslay experiment)… The atomic no of an atom only refer to the no of proton not electron… Because sodium cation has atomic no 11 and having 10 electrons… And it’s atomic no is 11 not 10
Correct Answer is B: proton Number or Atomic number
Answer should be atomic number or protons .. Bcz atomic numbers are no.of protons in nucleus of atom..admin plz update
Protons is correct answer instead of Electrons please correct it. Thanks
Elements in the periodic table arrange in order of proton number not electron number.
Proton is correct answer.
Proton
it should be atomic no or no of protons because electrons can be lost or gained by elemts.
Proton number
It’s Proton
Please do search online to know about right option.
Its common mistake of choosing electron
Position of element is based upo on atomic no because electrons r not stable n then loss r gain but in atomic no proton present in nucleus and the stable thats why atomic no is correct
Proton right ans kindly correct it.
If there is no choice of atomic number, Proton is correct i.e. always equivalent to atomic number unlike electron.
The answer should be atomic number or both electron and proton, the atomic number represents the number of electrons and protons
Proton is right ans
Correct it most of the questions are wrong kindly correct.
