Electronegativity
REDOX
Main Group
100

This group contains metals that are very reactive and readily form in the +1 oxidation state.

What are the alkali metals?

100

This periodic trend is based on increasing n, and increases down a group and across a row.

What is atomic size?

100

Electronegativity trends lead to these types of relationships where chemicals not in the same group or row have similar properties. 

What are diagonal relationships?

100

Elements on the left side of the periodic table, such as Lithium and Magnesium, act as these. 

What are reductants? 

100

Process used to obtain sodium from rock salt

What is the Downs process? (or what is electrolysis?)

200

This group contains elements that readily form in the -2 oxidation state. The majority of the elements in this group are nonmetals. 

What are the Chalcogens?

200

This periodic trend is based on how much an element wants to become an anion.

What is electron affinity?

200

This electronegativity scale is based off of bonding. 

What is the Pauling electronegativity scale?

200

Elements on the right side of the periodic table, such as fluorine and chlorine, act as these. 

What are oxidants? 

200

Element most similar to lithium on the periodic table.

What is magnesium? (as a result of the diagonal relationship)

300

This group contains the most electronegative element, and these elements readily form ions in the -1 oxidation state. 

What are the halogens?

300

This periodic trend decreases down a group as the lowest incompletely occupied atomic orbital becomes larger and roughly increases across a row as the effective nuclear charge increases. 

What is electronegativity? 

300

This electronegativity scale bases electronegativities off of electron affinity and ionization energies. 

What is the Mulliken scale? 

300

This element is the best reductant on the periodic table. 

What is Francium, Fr? 

300

Common source of magnesium on Earth

What is seawater?

400

This group contains classically inert elements, which readily form diatomic molecules.

What are the Nobel Gases?

400

This periodic trend decreases down a group due to valence orbitals becoming larger and increases across arrow because effective nuclear charge increases.

What is ionization energy?

400

This electronegativity scale considers electronegativity in terms of effective nuclear charge.

What is the Allred-Rochow scale?

400

This process occurs when a species reacts with itself to produce two or more stable products. 

What is Disproprotionation?

400

When paired with this element, boron can create "aromatic" compounds isoelectronic to carbon materials

What is nitrogen? (BN = CC)

500

This group contains metals, nonmetals, and metalloids, including antimony. 

What are the Pnictogens?

500

This type of element makes up most of the periodic table. Some characteristics of these elements include high thermal and heat conductivity. 

What are metals?

500

The most electronegative element. 

What is Fluorine?

500

These three types of diagrams give us information about REDOX of an element based on different oxidation states. 

What are Latimer, Frost, and Pourbaix diagrams? 

500

Well-known, regular, repeated use for excited cesium atoms

    What are atomic clocks?
