What is a noble gas?

Back

A noble gas is an element in Group 18 of the Periodic Table that is characterized by a full valence shell, making it very stable and unreactive. Example: Helium.

Define atomic radius.

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is the significance of the Periodic Table?

Back

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

Front

What are alkali metals?

Back

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

Front

What are halogens?

Back

Halogens are the elements in Group 17 of the Periodic Table, known for being very reactive and typically forming salts with metals. Example: Chlorine.

Front

What is the trend in ionization energy as you move across a period?

Back

Ionization energy generally increases as you move from left to right across a period.
