Atoms (part #1)

Hi guys we’re going to talk about what atoms are made up of.

Atoms are made up of: Protons Neutrons and Electrons. All of them have a charge except for Neutrons. Protons have a positive charge. Electrons have a negative charge. And Neutrons don’t even have a charge. They are neutral.

I know you might be confused but I will explain. P stands for proton. E stands for electron. And N stands for neutron. The plus sign means positive charge. The minus sign means negative charge. And if there is no sign that means it has no charge.

FUN FACT: 1 Way to make a Neutron is to smash together a Proton and an Electron because positive and negative make neutral. And that is what happens to make a neutron Star . keep an eye out for more information about neutron stars in an upcoming post.

So what is happening in this drawing is. I drew a proton and electron are smashing together to make a neutron.

Together Protons Electrons and Neutrons make an atom. Not all atoms have a neutron. For example one type of hydrogen atom has just one proton and electron no neutrons. In an atom the protons and (sometimes) neutrons will be in the nucleus of the atom. And the electrons will be buzzing around the nucleus.And the nucleus is where the protons and neutrons will be.

In this drawing I drew one type hydrogen atom with it’s proton and electron.

And you might say: well why don’t the electrons just buzz away? Good question. The reason why is because of the electromagnetic force. In the next post I will talk about the four forces!

In this drawing I drew a hydrogen atom with it’s proton and electron But I also drew the electron not going away

I wrote this from memory from what I learned in khan Academy
