Elements are arranged by the number of protons because it is the one system that can accurately sort the elements into their periods and groups with no exceptions. For example, if atoms were sorted by mass rather than number of protons, a couple of the elements would be switched messing up the periods and groups of the table.
No, they are organized by numerous factors (such as free electrons and number of orbital shells) but are given their periodic number based on their electrons.No. They are arranged by the number of protons which is the same as the number of electrons.
NO!!! Elements in a Period are arranged by Atomic No. / Proton No. If we take PERIOD 1. . the two elements are Hydrogen and Helium, in that order. H**ydrogen , Hel**ium are NOT in alphabetical order.
The elements in the periodic table are arranged by their atomic number, which represents the number of protons in the nucleus of an atom. This arrangement helps to group elements with similar properties together in columns known as groups or families.
Elements in the periodic table are arranged by increasing atomic number, which is the number of protons in the nucleus of an atom. This arrangement helps to group elements with similar properties together in columns called groups or families.
Elements are arranged in order of increasing atomic number. The atomic number is the number found at the top of each box on the Periodic Table. The atomic number is the number of protons in the nucleus of each atom of each element.
Number of protons are taken. They are arranged by number of protons. Mendeleev arranged elements first according to atomic number
Number of protons in the atom.
They are arranged according to the atomic number. The atomic number is the number of protons.
No, they are organized by numerous factors (such as free electrons and number of orbital shells) but are given their periodic number based on their electrons.No. They are arranged by the number of protons which is the same as the number of electrons.

According to the number of their protons
Mass number - the number of protons and neutrons present in the nucleus.
Yes they are.
