You are probably wondering what this table of colourful boxes is? Well you’ve come to the right place, I hope. What is it?
Well everything in the world is made up of elements, well almost everything, light, heat, this is energy, another story. And elements are a single type of atom, the periodic table is basically a table of all know elements to man. What’s in it?

To understand what’s in it we need to look at an atom and it subatomic parts. An atom is made up of an Electron(e-) this has a negative charge, Proton(p+) this has a positive charge and a Neutron(n) this is neutral. The C is the element symbol in this case Carbon. The 12 is the Atomic number, this is the number of protons and neutrons. The 6 is the Atomic mass, this is the number of protons which is also the number electrons. So 12-6=6 the number of neutrons. Periods and Groups

The periodic table is arranged into groups and periods. Periods are horizontal (rows) these show the number of electron shells and they go up left to right in Atomic number. So Potassium(K) on period 4 will have 4 electron shells. Groups, these are the columns going across except the transition metals. The group number show the number of electrons on the outer most shell. Group 0 does not apply to this rule because they are the noble gases, they however have the outermost electron shell full. Oxygen (O) will have 6 electrons in its outer shell. How is the Periodic Table Split?

Non-metals: These are the elements on right side of line, as well as hydrogen, which is, which is in-group 1 because it only has 1 electron on its outer shell. Non-metals cannot conduct electricity except carbon (in the graphite form) because it has 1 electron “free” this allows electricity to conduct in carbon but not as well as metals. So it’s used as a carbon resistor. They also can’t conduct heat well. This is again due to the fact that non-metals don’t have enough “free” electrons to share the thermal energy easily. Non-metals are dull and...
