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 the atomic number of lithium

Lithium (Li) has an atomic number of 3.

Step2: Find the electron - shell configuration

The electron - shell configuration of Li is 1s²2s¹. The outermost shell (valence shell) is the 2s shell which has 1 electron.

Step3: Draw the electron - dot diagram

We represent the nucleus and inner - shell electrons as the element symbol (Li) and place 1 dot around it to represent the valence electron.

Answer:

Li•
