Document Summary
Chapter 2: atoms and bonds: structure of an atom, energy levels: adding and subtracting electrons (think negatives, valence electrons: electrons in an atom"s outer shell. Electron distribution determines behavior of an atom: electronegativity: attraction of an atom for electrons of a covalent bond, atomic mass: sum of protons and neutrons. Atomic number: number of protons: use information in periodic table to answer: Ii. the process of an atom with an incomplete valence shell to try and. Covalen t : two atoms share electrons, formed between two nonmetals. : bonds between atoms of different charges, formed between metal and nonmetal. : when an atom is bonded to a more electronegative atom, the electrons of the bond are not shared equally, causing the charge to be unevenly distributed the electrons are shared equally because they have the same. : bond between two atoms of the same element, : hydrogen is attracted to a highly electronegative atom: hydrogen forms covalent bonds.
