Question

for each nonmetal below, identify how many covalent bonds (shared electron pairs) it forms with other atoms to fill its valence shell. element number of covalent bonds h c n o cl show periodic table

Explanation:

Step1: Determine H's valence - shell requirement

Hydrogen has 1 valence electron and needs 2 to fill its valence shell. It forms 1 covalent bond.

Step2: Determine C's valence - shell requirement

Carbon has 4 valence electrons and needs 8 to fill its valence shell. It forms 4 covalent bonds.

Step3: Determine N's valence - shell requirement

Nitrogen has 5 valence electrons and needs 8 to fill its valence shell. It forms 3 covalent bonds.

Step4: Determine O's valence - shell requirement

Oxygen has 6 valence electrons and needs 8 to fill its valence shell. It forms 2 covalent bonds.

Step5: Determine Cl's valence - shell requirement

Chlorine has 7 valence electrons and needs 8 to fill its valence shell. It forms 1 covalent bond.

Answer:

H: 1
C: 4
N: 3
O: 2
Cl: 1
