Ions Flashcards
How do you Represent Ions
You Represent Ions by writing a Negative symbol or a Positive symbol on the Right-hand Superscript depending on the charge.
Then you add a number before the symbol based on the net charge.
Define Covalent Bonds
A Covalent Bond (Molecular Bond) is a chemical bond that involves the sharing of electrons
What are the names of Compounds that form Covalent Bonds
Molecules
How are Molecules Represented
Molecular Formulas first indicate which elements are present and then tell you the number of atoms present in the subscript.
(N2H4)
How are Molecules Demonstrated
Molecules are represented using the ball and stick models
Define Ionic Bonds
Ionic Bonds are a type of chemical bonding that involves the electrostatic attraction between oppositely charged Ions.
(Elements completely transfer electrons to have a neutral outer shell and bond because of electrostatic attraction)
What are the name of Compounds that form Ionic Bonds
Formula Units
How are Ionic Bonds represented
Ionic Bonds are represented using the lewis dot structure
The element symbols will be surrounded by brackets
The right-hand superscript of each element will have a positive or negative number depending on the net charge and a number for the amount of electrons given away
The element that took the electrons will be represented using the Lewis Dot Structure
How are Binary Ionic Compounds ordered by name
When you combine two Ions, the positively charged Cation will go first and then the negatively charged Anion will go last.
Why aren’t Ionic Compounds Considered Molecules?
All Ionic Compounds do not exist as a single unit, but instead as a Crystal Lattice Structures of many of those atoms alternating in space
Define the Emperical Formula
The Emperical Formula gives information about the proportions of elements present in a molecule.
(It only gives the proportions and not the total number of atoms in that Molecule)
Define the Molecular Formula
The Molecular Formula gives you the elements and number of atoms present in a molecule.
Define the Structural Formula
The Structural Formula shows the arrangement of atoms in the molecule of a compound.
