they increase left to right
increase of protons and electrons
Protons gradually increase or decrease.
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.
As you go down the columns of the periodic table the number of protons (and electrons) in the element increase. As the atomic number increases, so does the radius at each electron shell.
# protons = atomic number.
There are 11 protons and 12 neutrons. And that does not depend on the periodic table. Sodium had 11 protons and 12 neutrons long before the periodic table, or even human, beings existed!
periodic number Z: the number of protons
The periodic table organizes the elements by atomic number (number of nuclear protons).
The atomic number on the periodic table is the number of protons for the element.
