{'graphite': [0, 0, 3, 9], 'carbon atom': [0, 0, 0, 4], 'pentagonal array': [0, 0, 0, 1], 'hexagonal array': [0, 0, 0, 1], 'structure': [7, 0, 5, 8], 'other carbon': [0, 0, 0, 1], 'square array': [0, 0, 0, 1], 'same plane': [0, 0, 0, 1]}

In graphite, each carbon atom is bonded to three other carbon atoms. This creates a layered structure where the carbon atoms are arranged in a hexagonal array. This means that the carbon atoms are all in the same plane, forming a flat, two-dimensional structure.

Option 1, which suggests that graphite forms a three-dimensional structure, is incorrect. Graphite is actually a layered material with atoms arranged in a 2D plane.

Option 3, which suggests that graphite forms a square array, is also incorrect. The arrangement of carbon atoms in graphite is hexagonal, not square.

Option 4, which suggests that graphite forms a pentagonal array, is also incorrect. The arrangement of carbon atoms in graphite is hexagonal, not pentagonal.

Therefore, option 2 is the correct answer as it accurately describes the bonding pattern of carbon atoms in graphite, where they are arranged in the same plane to form a hexagonal array.
