Document Summary
An atom is a nucleus composed of positively charged protons and neutrons (no charge) and is. Ionic - atoms with an ionic bonds are held together by giving each other electrons until they. Van der waals - forces that are determined by a balance of attraction and repulsion charges. These are all chemical bonds that hold elements together. Covalent - atoms with an covalent bond are held together by atoms that share electrons to fill. Describe the structure of an atom (nucleus with protons and neutrons, electron cloud). surrounded by an electron cloud made f negatively charged electrons. The majority of the atom is made up by the nucleus. An element is a group of the same atoms that all have the same number of protons. Describe the difference between covalent, ionic and van der waals bonds. their electron cloud - strong bond both have a full electron cloud - strong bond between nucleus and atoms - weakest type.
