Ionic Bonding - Coggle Diagram
Ionic Bonding
Ion
Atom loses or gains electrons to form ions
Ions are charged particles
Ions can be positively-charged or negatively-charged
Positively-charged = cations
Negatively-charged = anions
Formation of Cations and Anions
Cations
Atoms lose electrons to form positively-charged ions to achieve noble gas configuration
Anions
Atoms gain electrons to form negatively-charged ions called anions to achieve noble gas configuration
Chemical Formulae of Ionic Compounds
Constructed by balancing the charges on positive and negative ions
All positive charges must equal all the negative charges in an ionic compound
Transferring electrons
Ionic bonds are formed between metals and non-metals
Done through the transfer of electrons from metals to non-metals
Naming of chemical symbol
Metallic element written first
Number of atoms written as a subscript to the right of atoms symbol
Subscripts are simplest set of whole numbers
No subscript '1'
If there is more than one polyatomic ion, the formula of that ion is placed within brackets
