Intro to Covalent and Ionic
Can a bond be 100% ionic or covalent?
No, it is a continuum with few exceptions!
What two types of elements are in an ionic nomenclature?
One metal element and one non-metal element!
What two types of elements are in Covalent nomenclature?
Two non-metal elements!
What would be the correct formula for Calcium Chloride?
CaCl2!
What would be the correct name for XeF6?
Xenon hexafloride!
What determines if a bond is Covalent or Ionic bond?
The electronegativity!
Which ion in a ionic equation is first when naming it?
A cation/ positive ion!
What do the prefixes used in the nomenclature represent?
The number of atoms in each element!
How would you name (Nh4)2O?
Ammonium Oxide!
What would be the correct formula for Tetra arsenic decoxide?
AS4O10!
If the electronegativity difference of a bond is low, is it ionic or covalent?
It is covalent!
Transition metal use what to indicate charge?
Roman numerals!
What do you NOT do when writing out the first element?
Not use the prefix mono!
What would be the correct formula for Vanadium (V) Nitride?
V3N5!
What is the correct formula for Dicarbon Hexabromide?
C2Br6!
Is the nomenclature the same for ionic and covalent the same?
No they are different based off of prefix!
An anion ends in -ide unless what?
It is a polyatomic ion!
How do you write out the nomenclature if it has a double O OR an AO combo?
Drop one of the O or the A depending on which combo!
How would you name Ca3(PO4)2?
Calcium Phosphate!
What would be the correct name for CO?
