VS Chemical Bonding

Ionic and Covalent Bonds

attractive force that holds different atoms together to make a compound chemical bond
two or more elements joined together in a certain ratio compound
a diagram to show how the atoms in a compound are connected; uses chemical symbols to represent the atoms structural formula
results in a substance that is a strong solid with a high melting/boiling point crystal (network structure)
determines whether a substance is a solid, liquid or gas at room temperature attractions between the molecules
interact to form bonds between atoms valence electrons
number of valence electrons to make a "full" outer shell in MOST elements 8
bonds formed when a positive ion and a negative ion are attracted to each other ionic bond
form positive ions (are electron donors) metals
form negative ions (are electron takers) nonmetals
formed by the transfer of electrons ionic bond
tells the ratio of ions in an ionic compound formula unit
do not conduct electricity unless they are dissolved in water ionic compounds
bonds that form between metal atoms that cause them to pack together and allow them to conduct electricity metallic bonds
bonds formed between nonmetals covalent bonds
bonds formed between a metal and a nonmetal ionic bond
bonds formed when atoms share one or more pairs of valence electrons covalent bonds
a covalent bond in which the electrons are shared equally nonpolar covalent bond
a covalent bond in which the electrons are NOT shared equally, forming a sort of positive end and negative end of the molecule polar covalent bond
