Chapter 13 - Chemical Bonding
Question | Answer |
---|---|
chemical bonding | the joining of atoms to form new substances |
chemical bond | a force of attraction that holds two atoms together |
valence electrons | the electrons in the outermost energy level of the atom |
ions | charged particles that form during chemical changes when one or more of the valence electrons transfer from one atom to another |
covalent bond | the force of attraction between the nuclei of atoms and the electrons shared by the atoms |
crystal lattice | a repeating three-dimensional pattern of ions |
ionic bond | the force of attraction between oppsitely charged ions |
molecule | a neutral group of atoms held together by covalent bonds |
metallic bond | the force of attraction between a positively charged metal ion and the electrons in a metal |
how many valence electrons are needed to fill the outermost energy level | 8 or for helium and hydrogen 2 |
how can you tell how reactive an element is | an element with 8 electrons isn't reactive at all, and an element with 1 valence electron is the most reactive |
What are common diatomic molecules | the are simple molecules consisting of two atoms bonded together; including oxygen nitrogen and hydrogen |
What are the properties of metals? | good conductors, malleable, ductile, and shiny |
