use the periodic table or graphic in lesson. how many valence electrons does carbon have?
Answer
Answer:
4
Explanation:
Step1: Locate carbon on periodic table
Carbon is element 6.
Step2: Determine electron configuration
Carbon's electron - configuration is 1s²2s²2p².
Step3: Count valence electrons
The outer - shell (n = 2) has 4 electrons (2s²2p²), so valence electrons = 4.
