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
