Answer:
The answer is B. antimony
Explanation:
The periodic table of the elements shows the chemical elements ordered by their atomic number, electron configuration and chemical properties.
The periodic table has seven rows (horizontal) called periods and in 18 columns (vertical) called groups.
Periods represent the energy levels that an atom has. Thus, since vanadium (V) has four energy levels, it therefore belongs to the fourth period.
Helium belongs to period 1, boron belongs to period 2, and antimony belongs to period 5. This means that they have 1,2 and 5 energy levels respectively:
So: antimony has five energy levels.
