Question

fill in the blank question
the electron dot diagram for hydrogen consists of the symbol and dot(s). the electron dot diagram for helium consists of the symbol and dot(s).

Explanation:

• Electron - dot diagrams (also known as Lewis dot diagrams) use the symbol of an element to represent the nucleus and inner - shell electrons, and dots to represent the valence electrons.
• Hydrogen (\(H\)) has 1 valence electron.
• Helium (\(He\)) has 2 valence electrons.

Answer:

The electron dot diagram for hydrogen consists of the symbol \(H\) and \(1\) dot(s). The electron dot diagram for helium consists of the symbol \(He\) and \(2\) dot(s).
