4. diagram: turn on show electron dot diagram. the valence electrons of an atom are shown in an electron dot diagram. each dot represents a valence electron. draw the electron dot diagram for neutral lithium: ________
Answer
Explanation:
Step1: Determine lithium's atomic number
Lithium (Li) has atomic number 3.
Step2: Find number of valence electrons
The electron - configuration of Li is 1s²2s¹. So it has 1 valence electron.
Step3: Draw the electron - dot diagram
We write the symbol Li and place 1 dot around it.
Answer:
Li•
