Chemical Bonding Flashcards
atoms bond togther to form what ?
Atoms
Bond together to form
molecules or compounds
Why do atoms bond together
Atoms bond togetner to attain
a noble gas configuration.
They bond together to
attain stability associated with
complete outer shell. (octet Rule)
What is valence electrons
The total outermost shell
electrons.
The outermost shell is called
“valence shell”
The number of valence electrons correspond with
the group number of the electrons in the periodic table
What are lewis diagrams
They are dot and cross diagrams showing yhe valwncw electrons only
What is covalent bonding
Binding firmed when atoms share valence electrons to obtain nobal gas formation
Between what type of atoms does covalent bonding occure
Between non mental atoms
Whats is complex notation
When u show the amount of bond pairs between two non metals
(Showed by a line )
Eg F — F
O = O
What is ionic bonding
Bonding which occurs between a metal and a non metal
What does ionic bonding involve
Its involves the complete tranfer of electroms from the metal to the non metal
In ionic bonding
What happens to the metal
What happens to the non metal
Therefore how are the ions brought together
The metal looses electrons to form a positively charged ion
The non metal gains electons to formed a negetively charged ion
Oppositely charged ions are rvought togther by an electrostatic force of attraction
