What is the structure of an atom? - ✔✔Nucleus protons electrons neutrons
Define nucleus - ✔✔Control center of the cell
Define proton - ✔✔positively charged particle inside the nucleus
Define neutron - ✔✔A neutral particle that is found in the nucleus of an
atom.
Define electron - ✔✔a negatively charged subatomic particle
What are covalent bonds? - ✔✔a chemical bond that involves the sharing
of electron pairs between atoms
What are ionic bonds? - ✔✔transfer of electrons
