question 2\nis oxygen a metal or a nonmetal? how many valence electrons does an oxygen atom have?
Answer
Answer:
Oxygen is a non - metal. An oxygen atom has 6 valence electrons.
Explanation:
Step1: Identify element type
Oxygen is in group 16 of the periodic table and is a non - metal.
Step2: Determine valence electrons
Oxygen has an atomic number of 8. Its electron configuration is 1s²2s²2p⁴. The electrons in the outermost shell (n = 2) are the valence electrons, and 2 + 4=6.
