Question

how many electrons does carbon have in its valence orbital? ______ (number)
question 22 1 pts
water is a compound but not a molecule.
true
false

Explanation:

Step1: Recall carbon's electron configuration

Carbon has an atomic number of 6. Its electron - configuration is 1s²2s²2p². The valence shell is the second shell (n = 2), and the number of electrons in the 2s and 2p orbitals combined is 4.

Step2: Analyze water's nature

A molecule is formed when two or more atoms are held together by chemical bonds. A compound is a substance made up of two or more different types of elements chemically combined. Water (H₂O) is composed of two hydrogen atoms and one oxygen atom held together by covalent bonds. So, water is both a molecule and a compound.

Answer:

4
False
