which are components of electron dot diagrams?
□ dots representing valence electrons
□ a dot representing the nucleus
□ the chemical symbol of the element
□ circles representing energy levels
□ dots representing inner electrons

Explanation:

Electron dot diagrams (also known as Lewis dot structures) use the chemical symbol of the element to represent the nucleus and inner - shell electrons. The valence electrons are represented as dots around the chemical symbol.

• Dots representing valence electrons: Correct. This is a key component as valence electrons are what is shown in electron dot diagrams.
• A dot representing the nucleus: Incorrect. The nucleus is not represented by a single dot. The chemical symbol represents the nucleus and inner - shell electrons.
• The chemical symbol of the element: Correct. It is the central part of the electron dot diagram.
• Circles representing energy levels: Incorrect. Electron dot diagrams do not use circles for energy levels.
• Dots representing inner electrons: Incorrect. Inner electrons are not shown as separate dots; they are represented by the chemical symbol.

Answer:

dots representing valence electrons, the chemical symbol of the element
