What type of reaction has this base formula:
A + B --> AB
Synthesis
What is Mr. Bergsma's age?
24
How many neutrons does Ar have?

Why do we only write the roman numerals for transition/multivalent metals?
The purpose of the roman numerals is to state the charge, we already know the charges for non-transition/multivalent metals
What is the number called that we place in front of a compound in balancing?
Coefficient
What type of reaction is shown below:
LiF + BeO --> Li2O + BeF2
Double displacement
What colour are Mr. Bergsma's eyes?
Blue
What is an anion?
A negatively charges ion
True or false?
Crisscross your charges for all types of naming
False
Do not crisscross or incorporate charges for molecular naming
When do you need to incorporate diatomics in writing chemical equations?
ONLY when they are a single atom (by themselves)
How do you know what element in a compound is replaced in a single displacement reaction?
The single element will replace the element in a compound that plays the same role.
Ex. Anion replaces and anion, cation replaces a cation
How old is Mr. Bergsma?
24
Where is each subatomic particle located in an atom?
Neutron + Proton = nucleus
Electron = orbiting nucleus
Using words, explain how we would name an ionic compound involving a polyatomic ion
Write the metal name and then the polyatomic ion (do not change the ending)
In the case of ammonium, write ammonium followed by the non-metal with an "ide" ending
