Title: Ionic & Covalent Bonding
Description: Hello! This is a pretty basic yet comprehensive review of Ionic and Covalent Bonding :--) It\'s very easy to understand, as well! It helped me score high on my long quizzes and exams, and I hope that it would do the same for you :--)

IONIC BONDING
Stability
The Octet Rule
The noble gases are the chemical elements in group 18 of
the periodic table
...
Therefore, they rarely react with other
elements since they are already stable
...
They may accomplish this by either giving
electrons away or taking them
...
● are formed between a metal and a nonmetal
*atoms that have gained or lost electrons are called ions
○ metals
give
electrons
and
become
positively-charged cations
○ nonmetals take electrons and become
negatively-charged anions
● tend to be stronger than ionic compounds
● are formed between two nonmetals
○ transfer of electrons between nonmetals
● have high melting and boiling point
○ Why? Because ionic bonds are relatively strong;
thus, ionic crystals require a large amount of
energy to be broken apart
● generally have much lower melting and boiling points
● are poor conductor of electric current as solids
○ Why? In the solid state, the ions in an ionic
compound are locked into fixed positions by strong
attractive forces
...
The symbol for the cation is always written first,
followed by the symbol of the anion
...
Subscripts represent the number of ions of each
element in
