which statement accurately describes this illustration of a hydrogen atom and an oxygen atom? hydrogen has 1 valence electron and oxygen has 2 valence electrons. hydrogen has 1 valence electron and oxygen has 6 valence electrons. hydrogen has 1 valence electron and oxygen has 8 valence electrons. hydrogen has 2 valence electrons and oxygen has 6 valence electrons.
Answer
Explanation:
Step1: Recall hydrogen's electron configuration
Hydrogen has atomic number 1. Its electron - configuration is 1s¹, so it has 1 valence electron.
Step2: Recall oxygen's electron configuration
Oxygen has atomic number 8. Its electron - configuration is 1s²2s²2p⁴. The electrons in the 2s and 2p orbitals are valence electrons, so it has 6 valence electrons.
Answer:
Hydrogen has 1 valence electron and oxygen has 6 valence electrons.
