Periodic Table Review

Periodic Table Review

By Marissa Soto

Poll

How comfortable are you with understanding the Periodic Table and understanding the relationships between its elements?

• Extremely confident!

• I feel good but not 100%

• I remember only a little...

• What is the periodic table?

Periodic Table divisions:

• The Periodic Table is divided into groups and periods.

• Groups run up and down.

• Periods run side to side.

• REMEMBER: "The groups! The groups! The groups are in columns! The rows! The rows! The rows are periods!

Classifying Matter

• Elements: pure substances, on the Periodic Table

• Compounds: two or more elements; parts on the Periodic Table

• Mixtures: two or more substances MIXED; not on Periodic Table

Multiple Select

Choose all the items that are elements.

• NaCl (table salt)

• Sulfur

• O₂

• Water

• Air

Periodic Table Groups:

• Groups are also called "families"

• REMEMBER*: Groups are in "columns!"

• Groups share common characteristics; i.e. All group 1 elements explode in water. All group 18 elements DON'T react.

• Fluorine and Chlorine are in the same GROUP (17), SO, they share the same PROPERTIES.

Multiple Choice

Groups run:

• up and down

• left to right

Multiple Select

Choose all of the items that are compounds.

• NaCl (table salt)

• Sulfur

• O₂

• Water

• Air

Multiple Choice

Periods run:

• up and down

• left to right

Multiple Select

Choose all of the items that are mixtures

• NaCl (table salt)

• Sulfur

• Air

Groups & Periods

• Groups: Columns; up & down, similar properties. ⬆️ ⬇️

• Periods: Rows; left to right; increasing atomic ➡️ ⬅️

Multiple Choice

Which two elements share common characteristics based on the periodic table?

• Sodium and Magnesium

• Chlorine and Sulfur

• Argon and Neon

• Calcium and Bromine

Multiple Choice

Which element is similar to Li?

• Be

• K

Periodic Table Periods:

• Periods run in rows.

• Each period has the same number of electron shells. i.e. Hydrogen and Helium have 1 electron shell. Lithium and Boron have 2.

• This means each period has the same number of ENERGY LEVELS!

Multiple Choice

Which element is similar to Mg?

• Ca

• B

Multiple Choice

How are the 3 elements in the picture organized on the periodic table?

• Niobium and cobalt have the same energy levels.

• Cobalt and scandium have the same energy levels.

• Cobalt and scandium have the same characteristics.

• Niobium and cobalt have the same characteristics.

Multiple Choice

Which element is similar to B?

• C

• Al

Metals, Metalloids, and Nonmetals

• The periodic table is divided into 3 types of chemicals

• They are in alphabetical order: 1. Metal, 2. Metalloid, 3. Nonmetal

• Metals are the largest group

• Metalloids are the smallest group between metals and nonmetals.

Multiple Choice

Which element is similar to F?

• Ne

• Cl

Multiple Choice

Metals are on the:

• Left side

• Right Side

• Stairstep

Multiple Choice

Which element is similar to He?

• H

• Ar

Multiple Choice

Metalloids are on the:

• Left side

• Right Side

• Stairstep

Reactivity

• ability of a substance to react

• decreases left ➡️ to right ⬅️

• Group 1 and 17 are the most reactive

• Group 18 Noble Gases are least reactive, stable

Multiple Choice

Nonmetals are on the:

• Left side

• Right Side

• Stairstep

Multiple Choice

Which element is the least reactive?

• Li

• Ne

• B

• C

Multiple Choice

Which element is the least reactive?

• Mg

• Na

• C

• S

Multiple Choice

Which choice shows the elements in order from most reactive to least reactive. Sr, K, Cl, P

• Sr, K, Cl, P

• K, Cl, Sr, P

• K,P, Sr, Cl

• K, Sr, P, Cl

Metals

• Metals are on the left side of the table.

• Characteristics include: malleable, ductile, shiny, and conductive (electricity and heat)

Metalloids

• Metalloids are on the stairstep between metals and nonmetals.

• Characteristics include: somewhat malleable, a little ductile, somewhat shiny, and conductive at high temperatures

Nonmetals

• Nonmetals are on the right side of the table.

• Dull, brittle, non-conductors

Metals, Nonmetals, Metalloids

• Metals: ductile, malleable, luster, solids

• Metalloids: properties of metals & nonmetals

• Nonmetals: brittle & dull

Multiple Choice

A student is studying a mystery substance. It breaks easily. It has a very dull luster. It doesn't conduct any electricity. What is the most likely substance this is?

• Metal

• Metalloid

• Nonmetal

Multiple Choice

Students in Mrs. Clark's science class are investigating a substance that has the following properties

-shiny

-bends easily

-hard, not easily broken

Based on these properties how would you classify the substance?

• metal

• nonmetal

• metalloid

Multiple Choice

The same student works with a new substance. He concludes it conducts electricity very well. It has a very shiny luster. When he hammers it, it simply dents and flattens. What is the most likely substance type?

• Metal

• Metalloid

• Nonmetal

Multiple Choice

Which best describes the sequence of the elements in Period 5 of the periodic table?

• highly reactive gases, relatively nonreactive metals, metalloids, very nonreactive gases, nonreactive nonmetals

• highly reactive metals, relatively nonreactive metals, metalloids, reactive nonmetals, nonreactive gases

• nonreactive gases, metalloids, nonreactive metals, highly reactive metals, highly reactive gases

• nonreactive gases, nonreactive metals, highly reactive metals, metalloids,

  reactive nonmetals, reactive gases

Multiple Choice

The third substance the student works with is a little brittle. It is just a little shiny. When he tries to conduct electricity through it at first, it doesn't conduct, but upon heating up, it does start to allow electrons to flow. What is the most likely substance type?

• Metal

• Metalloid

• Nonmetal
