by subtracting the atomic number from the mass number. the atomic number is the one under the element's symbol and the mass number is the one above the element's symbol.
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!
True. Row number on the periodic chart will be the same as the shell number.
chemist used the Periodic Table to make it easier for them to figure out elements.as there are many valuable information(atomic no. 4 example)they can always have the chart with them and see them when they are doing experiments.taching,etc
Arsenic
You can "figure out" by checking the Periodic Table :D
The element AU on the periodic chart stands for gold.
Neutrons are not given directly on the periodic table. However the number of neutrons can be indirectly calculated. Mass number = Number of protons + number of neutrons
Look on a periodic table of the elements. If you can't figure it out from there, you don't really need to know.
12 neutrons
It is called the Periodic Table of Elements.
No

You know how many protons and neutrons are present. You can also figure out what element it is if you happen to have a periodic table of elememts.
