Ch 9.1/9.2: Atomic Properties and Chemical Bonds, Ionic bonding model

ionic bonding involved __sharing/transfer___ of electrons betweeen metals and nonmetals / nonmetals

transfer, metal and nonmetals

Steps for leiws dot sturcture

1. count total atoms (including subscript)

2. Place central atom

3. Connect with bonds (each is 2e^-)

4. Complete octects

define lattice energy

energy required to separate ionic solid into gaseous ions

lattice energy defines the strength of the ___.

ionic bond

what factors determien lattice energy and what is more important

ionic size, ionic charge. ionic charge is more important

what is trend for lattice energy

as ionic size increase, lattice energy decreases. (lattice energy decreases down a group)

as ionic charge increases, lattice energy increases.
