Question

1. use a periodic table to type in the correct answer for each blank. (see companion material attached) type the number of electrons that are needed to satisfy each element octet. c n o f ne

Explanation:

Step1: Find valence electrons for C

Carbon (C) has 4 valence electrons. To reach an octet (8 electrons), calculate: $8 - 4 = 4$

Step2: Find valence electrons for N

Nitrogen (N) has 5 valence electrons. To reach an octet: $8 - 5 = 3$

Step3: Find valence electrons for O

Oxygen (O) has 6 valence electrons. To reach an octet: $8 - 6 = 2$

Step4: Find valence electrons for F

Fluorine (F) has 7 valence electrons. To reach an octet: $8 - 7 = 1$

Step5: Find valence electrons for Ne

Neon (Ne) is a noble gas, it already has 8 valence electrons (a full octet). So: $8 - 8 = 0$

Answer:

C: 4
N: 3
O: 2
F: 1
Ne: 0
