Question

carbon has 4 valence electrons. hydrogen has 1 valence electron. how many hydrogen atoms would form chemical bond(s) with one carbon atom?a 1b 2c 4d 8

Explanation:

Step1: Understand valence electrons and bonding

Carbon has 4 valence electrons. To achieve a stable electron configuration (like noble gases), it needs to share 4 electrons.

Step2: Consider hydrogen's contribution

Each hydrogen atom has 1 valence electron. One hydrogen atom can share 1 electron.

Since carbon needs to share 4 electrons and each hydrogen shares 1, the number of hydrogen atoms is \(4\div1 = 4\).

Answer:

C. 4
