There are many different types of classification on the periodic table. Some of the classifications are metals, transition metals, metalloids, and non-metals. Some of the elements that are metals are Zn and the ones that are in the columns 1-12. The ones that are non-metals are the ones that fall under the columns 13-18.
You can tell how many protons are in an element because it has a number in the top left hand side of the element and that is the same to find the electrons. The electrons and the protons are the same thing and also called the atomic number. You can tell how many neutrons are in an element by taking the atomic mass minus the number of protons and that will get you ow many neutrons.Valence electrons are the electrons on the outer most shell. Also they are the outer most electrons that dictate the properties of the atom and are involved in chemical bonding.
Elements on the periodic table are in groups and periods because periods do not have the same number of valence electrons. Each period has a new energy level. Groups have same valence electrons, also elements within the same group have similar chemical properties.
Octet Rule: The outer ring wants 8 electrons!
The difference of physical and chemical properties is that chemical is a characteristic of a substance that can be observed only when the identity of the substance is changed. A physical property is a characteristic of a substance that can be observed without changing the identity of the substance. They are the same because
Evaporation is a physical property when water evaporates, it's still water, no new substance is created or destroyed. Therefore it's a physical change.

Volume=L*W*H It is the amount of space the object takes up. 1 cm./ cubed is the same as 1ml.
Mass is measured in grams.
V=M/D so M=V*D and D=M/V
