Atomic Structure
What did Thompson's plum pudding model consist of?
Thomson's model was a sphere of positive charges with negative electrons stuck to the sphere.
What's a Proton?
The proton is a subatomic particle with a positive electrical charge.
What is a Suspension Mixture and what is an example of it?
Suspension is a type of heterogeneous mixture where solid particles do not dissolve in a liquid solution.
Write the name of the IONIC Compund: PbCl2
The answer is: Lead (II) Chloride
Name the three levels of danger for Whmis.
Yellow= Warning, Orange= Caution and Red is danger.
What does the Rutherford Model Consist of? How did they find the nucleus?
The Rutherford model consists of electrons that move around in a fixed orbit. The Bohr model was the first model that had the Nucleus and it was discoverd using the gold foil experiment.
What's The difference between an Ionic and Molecular Compound?
Ionic consists of a Metal and Non-Metal, Molecular is just Non Metals.
What's The difference between A Homogeneous and a Heterogeneous Mixture?
A Homogeneous Mixture is hard to distinguish different particles, A heterogeneous mixture has different particles that can be distinguished by the human eye.
Write the name of the IONIC Compund: Fe2S3
Iron (ll) Sulfide
Name the Element (with prefixes): Na2O3
How many electrons sit on the valence shell for Sodium (Na)?
1
What does WHMIS stand for?
Workplace Hazardous Materials Information Systems.
What type of chemical reaction happens when the combustion of iron is mixed with pure oxygen?
It's a bit of a physical and chemical change, but mostly a chemical change
Name the Ionic formula to compound: Nickel (ll) Bromide
NiBr2
16.7 Moles
What is the current Atomic Model, and what does it consist of?
What are 3 types of Metals on the Periodic Table?
Metals, Metalloids and NON-Metals.
Is Copper and Nitric Acid a Physical or chemical Solution?
Chemical Solution.
Name the ionic formula to compound: Lead (ll) Fluoride
PbCl2
Carbon difluroide
How many electrons sit on the Valence shell for Nitrogen?
5
In an ionic compound why is it that a metal wants to always give away its electrons and a nonmetal wants to receive electrons?
Metals like to lose valence electrons to form cations to have a fully stable octet. They absorb energy (endothermic) to lose electrons. The electron affinity of metals is lower than that of nonmetals.
What is a Colloid and what is an example of it?
A colloid is a type of mixture in which particles do not fall out due to typical filtering methods, but can be separated out using special methods such as centrifugation.
Example (Milk)
Name the ionic formula to compound: Tin (IV) Sulfide
SnS
