proton, neutron, electron
Which 2 types of elements need to bond in order to form an ionic compound?
(Word Bank: Metals, non-metals, metalloids)
Metals and non-metals need to bond together
Which 2 types of elements need to bond in order to form an ionic compound?
(Word Bank: Metals, non-metals, metalloids)
Non-metals and non-metals
What is a reactant?
A chemical you start with (on the left side of the arrow)
What is my full name?
Kimberly Du
What are valence electrons?
Electrons located on the outermost orbital of an atom
What method do you use to find the chemical formula of ionic compounds?
Criss-Cross method
How do you name a covalent compound?
Like how you'd name an ionic compound but with prefixes.
What is a product?
Chemical(s) that you end with after a chemical reaction (on the right side of the arrow)
Who's birthday (in our squad) is coming up next???
Cici's birthday!!!
What particle in an atom is involved with bonding?
Proton, neutron, or electron?
Electron
Name this chemical: Ca3N2
calcium nitride
What is the chemical formula for a carbon atom bonding to 4 hydrogen atoms?
CH4
What are the elements in the chemical reaction below?

Zinc, copper, and chlorine
WHAT ARE WE CELEBRATING THIS MONTH THAT WE SHOULD BE CELEBRATING ALL YEAR ROUND ANYWAYS
Black History Month!!!
What is an atom?
The smallest unit of matter that makes up a chemical element
What is the chemical formula for potassium sulfide?
K2S
What is the name for NH3?
nitrogen trihydride
(or ammonia!!)
List the 5 types chemical reactions
Synthesis/combination, decomposition, combustion, single replacement/displacement, double replacement/displacement
Which midterm are you technically taking twice?
Chemistry :)
Which particle can I remove from an atom without changing an atom's charge?
Proton, neutron, or electron?
Neutron, because they have NO charge
List the 4 steps of the Criss-Cross method
1) Write ions using charges
2) Criss-cross the charges (without the +/- signs)
3) Rewrite closer together without the 1
4) Name the chemical. Name the first chemical normally, the second chemical ending with -ide
1) Draw Lewis dot symbol for each chemical
2) Connect single dots of one atom to single dots of another atom (if there are still more single dots, add another Lewis dot symbol for the chemical that has the least # of single dots)
3) Redraw neatly*
4) Write chemical formula by identifying the different elements and writing subscripts for each (except for 1)
5) Name it like you would an ionic compound but with prefixes
Which reaction is a synthesis reaction? EXPLAIN.
Which reaction is a decomposition reaction? EXPLAIN
a) H2CO3 --> CO2 + H2O
b) Na + Cl2 --> NaCl
a) is a decomposition reaction because H2CO3 breaks up into 2 products
b) is a synthesis reaction because Na and Cl2 are coming together to form 1 product
