Question

1. 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: ________

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•
