Metallic Bonds happen between which 2 types of elements?
Metals and metals!
Where are non-metals located on the periodic table?
Top, right corner!
How many valence electrons does Sulfur (S) have?
6 valence electrons!
Why do chemical reactions need to be balanced?
To obey the Law of Conservation of Mass!
What do you call electrons that have been released into the sea of eletorns?
Delocalized!
How many valence electrons are in C3H8?
20 valence electrons!
What charge will the Calcium ion have?
2+
Balance the following synthesis equation: __ H2 + __ S8 --> __ H2S

If nitrogen is bonded to fluorine, which element has a partial negative charge? Why?
Fluorine; it is more electronegative and hogs shared the electrons!
What is the formula for copper (II) phosphide?
Cu3P2
Why do number of collisions between molecules increase when the molecules are spread out (surface area increases)?
There are more particles with exposed area to collide when they are spread out!
What keeps metal cations together when you hit a chunk of metal with a hammer?
The attraction between the positive cations and the negative localized electrons!
