Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Determine the Atomic Number of Selenium
\text{Number of protons} = 34
- Selenium is element number 34 on the periodic table - The atomic number tells us the number of protons
Step 3:: Find the Number of Electrons
\text{Number of electrons} = 34
- In a neutral atom, the number of electrons equals the number of protons
Step 4:: Calculate the Number of Neutrons
\text{Number of neutrons} = 78 - 34 = 44
- To find neutrons, we need the mass number - The most common isotope of selenium is selenium- 78 - Mass number = 78 - Neutrons = Mass number - Atomic number
Final Answer
- Protons: 34 - Electrons: 34 - Neutrons: 44
