Atom
everything is made of molicules
molicules are made of atoms
when atoms are formed together it creats a molicule
the center of an atom is the nucelus
made of protons
positive electrical charge
made of nutrons
dont cary an electrical charge
electrons orbit around the nucelus
electrons cary a negetave charge
protons and electrons cancle eachother out
an atom is equaly charged
in the first shell there can be 2 elecrtons
in the second shell there can be 8 elecrtons
in the third shell there can be 18 elecrtons
and so on
.
the electrons in the outer shell is called a valence electron
the outer shell is called the valence shell
atoms form withother atoms useing the valence shell
atoms alwayss keep trying to fill its shel
electrons move in shells around the nuculus
