10 2  Textbook pages 12–13 An atom consists of an atomic nucleus with positive, negative, uncharged and positive, negative, uncharged. The atomic shell is made up of positive, negative, uncharged. Ions have more or less than. Neutral atoms have as many neutrons as protons. as many electrons as protons. as many electrons as neutrons. The atoms of noble gases have an outer shell that is fully occupied by. The noble gases are called (), (), (), (), (), (). Noble gases combine very easily with other elements. not good with other elements. only with precious metals. The main types of chemical bond are bond, bond, and bond. What belongs together? Connect the appropriate terms. Ions positively charged nucleus particles protons atoms or groups of atoms with more or fewer electrons atomic bond table salt ionic bond electron pair bond Ions with a deficiency of electrons are electrically positive, negative, neutral. One speaks of a metal bond when the substance only consists of negative metal ions and free electrons. consists of freely moving electrons and positive metal ions. positive metal ions. In addition to the electron pairs, substances with electron pair bonds also have many freely movable electrons. conduct electricity particularly well. are bad conductors.
