Q3 CHEMICAL BONDA Flashcards
these are the forces of attraction that holds atoms together
chemical bond
when a metal gives an electron to a non metal
Ionic bond
When two non metals share electrons
Covalent bond
An ion that loses electrons
Cation
An ion that gains electrons

The meaning of LEDS
Lewis Dot Structure
the outermost shell of an atom
Valence electron
The proponent of LEDs
Gilbert N. Lewis
How to determine valence electron from configuration
Add the last two electron configuration
properties of ionic compounds
- have high melting points and high boiling points
- hard and brittle
- conduct electricity when they are dissolved in water
types of covalent bonding
single bonds, double bonds, triple bonds
share 2 electrons
single bonds
share 4 electrons
double bonds
share 6 electrons
Triple bonds
electrons that are not bonded
Lone pairs
Electrons that creates the bond represented by a line
Bonding pairs
