Answer:
B.) trigonal bipyramidal
Explanation:
A.) is incorrect. In octahedral molecules, the central atom is bonded to six other atoms.
B.) is correct. In trigonal bipyramidal structures, the central atom is bonded to five other atoms.
C.) is incorrect. In tetrahedral molecules, the central atom is bonded to four other atoms.
D.) is incorrect. There is not such thing as a pyramidal molecular shape. This term is most likely referring to the shape, trigonal pyramidal. However, this is still incorrect. In trigonal pyramidal molecules, the central atom is bonded to three other atoms and a lone pair of electrons.
Answer:
The noble gases with complete outermost shell electrons.
Explanation:
Noble gases or inert gases do not react chemically with other elements because they have a complete configuration of their electronic shells. What drives chemical reaction is simply the exchange of electrons between two or more atoms. It can be a loss, a gain or simple sharing of electrons in order to achieve a complete configuration just like those of noble gases.
