ACADEMIC REVIEW

Who were each of the following scientists?

Democritus DaltonLavoisier Mendeleev

Thomson MillikanRutherford BohrSchrodinger

What are the steps of the Scientific Method?

Define homogeneous mixture vs. heterogeneous mixture

What are differences between mixtures (homogeneous and

heterogeneous) and compounds?

Explain how each are made.

What is the difference between an element and a compound?

What is a chemical formula of a compound? What does it tell you?

What are the 5 characteristics seen in chemical reactions?

Define Conservation of Mass.How does this pertain to

chemical reactions?

How do you change a number to scientific notation?

What is the difference between precision and accuracy?

How many significant figures are in the following numbers?

1.0052.4

0.000003405000

How do you convert from Kelvin to Celsius?

375 K to oC29 oC to K

How do you determine atomic number?

How do you determine mass number (not mass on periodic table – this is average atomic

mass!)

In a neutral atom, how do the protons and electrons compare?

How do the protons and electrons compare in a cation? Anion?

Define isotope.How does isotope compare to

parent element?

How many protons and neutrons are in the following:

5019X

6740Y

What are the 3 rules for electron configurations?

Explain each

What atomic model is used today?

Explain the model fully.

How did Mendeleev arrange the periodic table?

How is the periodic table arranged today?

There are 3 subatomic particle in an atom, which one determines the properties and reactivity of

the atom?

Where are each of the subatomic particles found in the atom?

What is the difference between representative elements and transition metals? (Location)

How are ions formed?

Explain each type.

How do you write an ionic symbol?

What is the difference between ELECTRON CONFIGURATION

AndORBITAL DIAGRAM

How do you determine the electron configuration of an

atom?

How does the electron configuration change from

element to ion?

Do metals lose or gain electrons?

Do nonmetals lose or gain electrons?

How do you calculate average atomic mass?

Explain in full detail

What is dimensional analysis?

Explain how you work out a DA problem

Label the different groups of the periodic table.

What is the formula for density?

Manipulate the formula to solve for mass and for volume.

What are 4 trends on the periodic table?

Explain each trend (describe using proton numbers, attraction,

shielding, energy levels)
