#1
Front (Question)
How do you know what shape the simple covalent molecule is?
Back (Answer)
The shape of simple covalent molecules depends on the number of bonds and the orientation of these bonds around the central atom.
#2
Front (Question)
What are the four shapes of covalent molecules called?
Back (Answer)
Linear Angular Trigonal pyramidal Tetrahedral
#3
Front (Question)
For angular, trigonal pyramidal and tetrahedral molecules, what does it mean when the central atoms lie in the same group?
Back (Answer)
If the central atoms lie in the same group, they have the same shape. e.g. carbon and silicon both lie in group 4 so they both have 4 outer electrons. This means when they are bonded to the same type of atoms, they will have the same shape.
