Bonds
Elements bond when they _______.
Share valence electrons.
Chemical change.
AB+CD ---> AC+BD Is what kind of replacement?
A double replacement.
If helium is in the 18th family, does it typically bond?
No.
Nitrogen is apart of the 15th family/column, would it typically bond with other elements (Assuming they do not have 8)?
Yes.
True or false, a hydrogen bond has only hydrogen.
False.
True or false, you can affect the rate of reaction for a chemical reaction by adding a catalyst.
True.
AB --> A+B
is an example of what type of equation?
decomposition.
What is the effect of a element having 7 valence electrons?
It is poisonous/explosive.
True or false, hydrogen DOES belong in the first family.
False.
Does hydrogen give away its valence electron to bond?
No.
True or false, you can change the rate of reactions for a physical reaction by increasing surface area.
True.
A+B-->AB is an example of what type of equation?
Synthesis.
Is an element with 8 valence electrons reactive or non-reactive?

Chemical change.
AB+C ---> AC+B is what kind of replacement?
A single replacement.
True or false, hydrogen needs the same amount of electrons to stabilize as any other elements.
What is the behavior of Alkali Earth Metals?
Dull, chalky, brittle, very reactive.
