How many valence (outer shell) electrons an element has.
the benefit is that you can tell the atomic number atomic mass its symbol and where it is on the periodic table
The Periodic Table tells you how many protons are in an atom by their Elemental Number. In other words, yes, the Periodic Table tells you how many protons are in an atom.
The columns tell you how many electrons the atoms have in their outer shells, which is a very essential information to understand reactions. Group 1 has 1 electron in the outer shell, group 2 has 2 electrons, etc.
simply yes
The atomic number of each element is on the periodic table. The elements are arranged on the periodic table in order of increasing atomic number.
Groups, 1 through to 8 (or 0) The internet will tell you details about the individual groups. P.S. The rows are called periods
The atomic number is equal to the number of protons and the number of neutrons in that atom.
No. Atoms on the Periodic Table are listed by element in order of atomic number, which is the number of protons an atom contains. The number of neutrons in the atoms of an element usually varies among several isotopes.
The columns of the periodic table are called groups (or families). All elements in a group have the same number of electrons in their outer orbital. Furthermore, since many chemical properties are determined by the location of the outermost electrons, elements in the same group will share many common properties.
The periodic table tells you chemical elements. :)

you cant its inposible just pay attention in class and u will find out.
