Karla Alvarez Chemistry Period One Subatomic Particle The electron is extremely small compared to all the other parts of the atom. It is negatively charged. The negative charge balances out the positive charge of the protons in the atom. Electrons are found in the electron cloud that surrounds the nucleus of an atom. The clouds are generally organized into shells. Electrons move at a quick pace‚ so you never really know where they are specifically. But after years of doing experiments‚ scientists

Essay-Subatomic Particles There are three different types of subatomic particles. The nucleus of an atom is composed of two different types of particles‚ protons and neutrons. Protons are positively charged atoms. The weight of a proton is one amu. Protons are located inside the nucleus and cannot move from inside the nucleus. The proton symbol is . Neutrons are also located inside the nucleus and have a neutral charge. Neutrons are also one amu like protons. Neutrons can move from the nucleus
