Subatomic Particles By Joshua Cohon
Nuclei • The nucleus lies at the center of the atom. • It contains the protons and neutrons. • It contains positive charge and no charge, so it is a positive charge. • Plural for nucleus is nuclei.
Protons • Protons have a positive charge. • The atomic number of an element tells how many protons there are in one of its atoms. • The element that has the most protons is unniloctium at 118 protons.
Neutrons • Neutron are neutral. • That means that they have no charge. • Sometimes, electrons and protons form together to make neutrons.
Electrons • Electrons orbit the nuclei. • Electricity is formed by electrons flowing. • Sometimes, they are found outside of atoms.
Quarks • Quarks build up subatomic particles. • There are three of them in all nuclei- contained particles. • In pions, there are two of them.
Fun Facts • When you see anti in front of the name of a subatomic particle, it is antimatter, the complete opposite of matter! • 1 million atoms stretch 1 inch!
Questions • How many quarks are in a proton? • Is a pion nuclei-contained? • What color quarks are there?
