What is an Electron Dot Diagram?

Back

An Electron Dot Diagram, also known as a Lewis Dot Structure, is a representation of the valence electrons of an atom. Dots are used to represent the electrons, and they are placed around the chemical symbol of the element.

How many valence electrons does Oxygen (O) have?

Back

Oxygen has 6 valence electrons.

Front

Which group of the periodic table contains elements with full valence shells?

Back

Group 18 contains elements with full valence shells.

What is the dot diagram for Neon (Ne)?

Back

Neon has 8 valence electrons, represented as: ••Ne••.

Front

What does a full valence shell indicate about an element's reactivity?

Back

Elements with a full valence shell are generally non-reactive or inert, as they do not need to gain or lose electrons.

How many valence electrons does Silicon (Si) have?

Back

Silicon has 4 valence electrons.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons are involved in forming bonds between atoms. They determine how an atom can interact with other atoms.
