Step 1:I'll solve this problem step by step, filling in the missing information about the element Chlorine.
Step 2:: Determine the Number of Protons
\text{Number of Protons} = 17
- The number of protons is equal to the atomic number - From the periodic table, Chlorine's atomic number is 17
Step 3:: Determine the Number of Electrons
\text{Number of Electrons} = 17
- In a neutral atom, the number of electrons equals the number of protons
Step 4:: Determine the Number of Neutrons
\text{Number of Neutrons} = 35.45 - 17 = 18.45 \approx 18
- Atomic mass is the total number of protons and neutrons - From the periodic table, Chlorine's atomic mass is approximately 35.45 - Number of neutrons = Atomic mass - Number of protons
Final Answer
Element: Chlorine Symbol: Cl Number of Protons: 17 Neutrons: 18 Electrons: 17 Atomic Number: 17 Atomic Mass: 35.45
