Explain why roman numerals are used in ionic compounds and give an example of a formula that uses roman numerals.
They’re used to represent the charge of the transition metal within the ionic compound.
Explain what an intermolecular force is and the 3 types of forces.
A type of force that keeps molecules together (unlike gases) and is not a bond; 3 types are Dipole-Dipole Attraction, Hydrogen Bonding, and the London Dispersion Forces
Explain the difference between accuracy and precision and draw an example of each.
Accuracy is how close a measurement to the accepted value, precision is how close measurements of the same item are to each other.

Explain what scientific notation is and solve this scientific notation problem: 4.0532 x 10^4. State the number of significant figures.
40532 and the number of significant figures is 5.
Draw the three early atomic models made by Dalton, Thomson, and Rutherford.
Explain and draw an accurate diagram depicting shielding, using words Repulsion and Attraction.

Explain why Sodium and Chlorine work so well together while bonding and give another example of two elements that would work well together using the same rule.
Sodium and chlorine are highly unstable due to their need for 8 electrons, and therefore sodium is able to get rid of its extra electron while bonding with Chlorine.
What is the Kinetic Molecular Theory (KMT)?
Determines the property of matter using its particles characteristics such as...
