Unit 3 (The Periodic Table) Test Review

Electron Configuration

100

Draw the electron configuration for the element Nitrogen (N). (The one with arrows in the boxes)

The teacher looks at the students' answer and determines if it is correct.

200

Which element is given this electron configuration?

5s²5p⁵

Iodine (I)

300

Which element is given the electron configuration below?

3s²3p²

Silicon (Si)

400

What is the electron configuration for the element Boron (B)?

2s²2p¹

500

Give BOTH the written valence electron configuration AND drawing (with arrows and boxes) for the element Chlorine (Cl).

3s²3p⁵

3s has two arrows in the box one up and one down. 3p has 5 arrows 2 in the first and second box one up one down and one pointing up in the last box. 

Trends

100

What are the three trends on the periodic table?

Electronegativity, Atomic Size/Radius, and Reactivity

200

Which element is the most electronegative on the periodic table?

Fluorine (F)

300

Which element has the largest atomic size/radius on the periodic table?

Francium (Fr)

400

In column 1 the Alkali Metal Family, which element is the MOST reactive metal?

Francium (Fr)

500

Which element has all of the following:

ZERO electronegativity

SMALLEST atomic size

Member of the Noble Gas Family

Helium (He)

S and P orbitals

100

True or False: The element Calcium (Ca) does NOT have a p orbital.

TRUE 

200

Draw the orbital diagram (s circle and p figure 8) for the element Oxygen (O).

1 circle with 2 electrons (dots) on it and 1 figure 8 with 4 electrons (dots) on it.

300

Write out the valence electron configuration for the element Bromine (Br) AND draw the orbital diagram (S circle and P figure 8).

4s²4p⁵

1 s orbital a circle with 2 electrons (dots) on it. 1 p orbital figure 8 with 5 electrons (dots) on it.

400

For the element Xeon (Xe) how many electrons will it's P orbital have?

6

500

For the element Radium (Ra) how many electrons would the P orbital have?

0 because it doesn't have a P orbital.

Shell Model

100

Which particles belong in the nucleus of an atom?

Protons and Neutrons 

200

Which particle goes on the shells of an atom?

Electrons

300

What are the electrons on the very last shell called?

Valence electrons 

400

Draw the correct shell model for the element Nitrogen (N).

7p7n in the nucleus. 2 shells with 2 electrons on the first shell and 3 electrons on the last shell.

500

Draw the shell model for the element Neon (Ne) AND tell me how many valence electrons this element has.

10P10N in the nucleus. 2 shells with 2 electrons on the first shell and 8 electrons on the last shell.

8 valence electrons

Periodic Table

100

How is the periodic table organized today?

Atomic Number

200

The column number tells us what about an element.

The row number tells us what about an element. 

Column number tells us the number of valence electrons an element has.

Row number tells us how many shells an element has.

300

What family does Fluorine (F) belong to?

Halogen

400

What are the three different categories of elements on the periodic table?

Metals, Non-Metals, and Metalloids

500

What is the trend of reactivity for BOTH metals and nonmetals on the periodic table? ALSO, which family on the periodic table does not have reactivity? 

Metals are more reactive as you go to the left and down the periodic table. 

Nonmetals are more reactive as you go up and to the right of the periodic table.

Noble gases do not have reactivity.
