Back

The innermost energy level can hold a maximum of 2 electrons.

Front

What are Groups on the periodic table?

Back

Groups are the vertical columns on the periodic table that categorize elements with similar chemical properties.

Front

What group does Sodium belong to?

Back

Sodium belongs to Group 1 of the periodic table.

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. Examples include helium, neon, and argon.

What is the significance of the Bohr Model?

Back

The Bohr Model illustrates the structure of an atom, showing electrons orbiting the nucleus in defined energy levels.

Front

How many electrons can the second energy level hold?

Back

The second energy level can hold a maximum of 8 electrons.

Front

What is the atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What is an element?

Back

An element is a pure substance that cannot be broken down into simpler substances by chemical means, consisting of only one type of atom.
