Step 1: Understand the problem
We need to find out how many electrons are in the valence shell of a phosphorus atom. The valence shell is the outermost shell of an atom, and it contains the electrons involved in chemical bonding.
Step 2: Recall the atomic structure of phosphorus
Phosphorus is the 15th element in the periodic table, and its atomic number is 15. This means that a neutral phosphorus atom has 15 electrons.
Final Answer
Phosphorus has 5 electrons in its valence shell.
