Answer:
0.1334
Explanation:
The number of atoms per unit (n) is given by:
The atomic packing factor (APF) is:
Answer: noble gases
Explanation: The elements whose valence shell is already filled is stable and thus don not lose or gain electron and thus do not react.
Halogen is the name given to fluorine family which have 5 valence electrons and thus easily gain electrons to attain stable configuration.
Alkaline earth metal is the name given to group 2 elements which have 2 valence electrons and thus easily lose 2 electrons to attain stable configuration.
Noble gases is the name given to group 18 elements which have 8 valence electrons and thus do not lose or gain electrons and thus is non reactive.
Alkali metals is the name given to group 1 elements which have 1 valence electrons and thus easily lose 1 electron to attain stable configuration.
