When atoms form covalent bonds, what happens to the space between the two atoms?
The space remains empty
The space is filled with hybrid orbitals
The space is occupied by ionic bonds
The space becomes a vacuum
Answer explanation
When atoms form covalent bonds, the space between them is filled with hybrid orbitals, allowing for the sharing of electrons.

What is the geometry of molecules with four electron cloud regions such as tetrahedral, trigonal pyramidal, or bent with single bonds (like H2O)?
Linear
Trigonal planar
Tetrahedral
Octahedral
Answer explanation
Molecules with four electron cloud regions, like H2O, have a tetrahedral geometry due to the arrangement of single bonds around the central atom.

What type of hybrid orbital is formed by one s and three p orbitals?
sp
sp^2
sp^3
d^2sp^3
Answer explanation
One s orbital and three p orbitals combine to form sp^3 hybrid orbitals, where one s orbital and three p orbitals mix together to create four equivalent sp^3 hybrid orbitals.
