molecular geometry
lewis structure
electron dot notation

1. choose the best answer.

which of these states that the repulsion between valence - level electron pairs surrounding the central atom in a molecule causes them to be as far apart as possible?
lewis structure
molecular geometry
vsepr theory
electron dot notation

Explanation:

Question 5

• VSEPR Theory is a theory to predict molecular geometry, not the shape itself.
• Molecular geometry specifically refers to the three - dimensional arrangement of atoms in a molecule.
• Lewis structure shows the bonding and non - bonding electrons in a molecule, mainly in 2D.
• Electron dot notation is used to represent valence electrons of atoms.

• Lewis structure is about representing electron distribution in a molecule, not about electron pair repulsion.
• Molecular geometry is the result of the arrangement, not the principle behind it.
• VSEPR (Valence - Shell Electron - Pair Repulsion) Theory states that valence - level electron pairs around a central atom repel each other and get as far apart as possible.
• Electron dot notation is for showing valence electrons of atoms.

Answer:

molecular geometry
