What I Have Learned About the Periodic Table

# data[].attributes.body
I had a lot of fun doing this  even though I didn't finish early. I learned that there was a shell around the nucleus.

The periodic table has 18 columns. each column is called a group or family. Each row in the periodic table is a period.the first element in a period is very reactive. The last is inactive.

Each block holds great information about the element. You can look at the elements properties by just looking what area the block is. The atomic number shows that a chromium atom's nucleus has 24 protons. The color yellow tells that chromium is a metal. There is also a chemical symbol and the name of the element.

Each element are made up of one atom. This atom has a special number of protons. Elements set of protons, neutrons, and electrons give the element it's properties. the scientists use these properties to place it into the three groups : metals, nonmetals, and metalloids.

Many substances are not made of just one atom.Atoms can form to make molecules.A molecule is the smallest thing of a substance that is made from more than one atom, but still has the properties of the substance.

The periodic table of elements sorts the elements known to the world.It sorts these elements into three groups, Metals, Nonmetals, and Metalloids. The elements are also arranged by the order of the atomic number.The atomic number increases from left to right and down line by line.

The squares of the periodic table are the names of different elements.

Each cloud or orbit surrounding each nucleus is called a shell.Each shell holds a maximum number of electrons.
Level 1/K:2 electrons
Level 2/L:8 electrons
Level 3/M:18 electrons
Level 4/N:32 electrons

Neutrons are neutral. They are important because they determine if an element is radioactive

Protons have a positive charge. The mass of a proton is 1800 times larger than a electron.

Electrons are smaller than protons and neutrons. Electrons are 1800 times smaller than protons.

Atoms can only be seen with a very powerful electron telescope. Atoms are the smallest particles of the world.It has the same properties of an element.
