Period Table

Front

What is the main purpose of the Periodic Table?

Back

The Periodic Table organizes all known chemical elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What are groups in the Periodic Table?

Back

Groups are vertical columns in the Periodic Table that contain elements with similar physical and chemical properties.

Front

What are periods in the Periodic Table?

Back

Periods are horizontal rows in the Periodic Table that represent elements with the same number of electron shells.

Front

Which group in the Periodic Table contains only nonmetals?

Back

Group 18, also known as the Noble Gases, contains only nonmetals.

Front

What is an alkali metal?

Back

Alkali metals are elements in Group 1 of the Periodic Table, known for being highly reactive and having one electron in their outer shell.

Front

Which alkali metal is the most reactive?

Back

Cesium is the most reactive alkali metal.

Front

What are transition metals?

Back

Transition metals are elements found in Groups 3-12 of the Periodic Table, characterized by their ability to form variable oxidation states and colored compounds.

Front

What are lanthanides?

Back

Lanthanides are a series of 15 elements from lanthanum (La) to lutetium (Lu) known for their high melting and boiling points and high electrical conductivity.

Front

What is the significance of atomic number in the Periodic Table?

Back

The atomic number represents the number of protons in an atom's nucleus and determines the element's identity.

Front

What are noble gases?

Back

Noble gases are elements in Group 18 of the Periodic Table, known for their lack of reactivity due to having a full valence shell.
