Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Identify the Element
Potassium is element number 19 on the periodic table. To determine its subatomic particle composition, we'll use the atomic number and standard atomic structure rules.
Step 3:: Determine Number of Protons
\text{Number of Protons} = 19
The number of protons is equal to the atomic number.
Step 4:: Determine Number of Electrons in a Neutral Atom
\text{Number of Electrons} = 19
In a neutral atom, the number of electrons equals the number of protons.
Step 5:: Determine Number of Neutrons
\text{Number of Neutrons} = 39 - 19 = 20
Number of neutrons = Mass number - Atomic number
Final Answer
- Protons: 19 - Electrons: 19 - Neutrons: 20
