WebOct 13, 2024 · Graphite: you can illustrate graphite’s structure by asking students to place a carbon atom in the centre of a triangle and place three further carbon atoms at the vertices to slowly build a single graphite sheet. Once constructed, students should be able to calculate the bond angle (360°/3 = 120°) around each carbon. WebVerified questions.
