How many valence electrons does an oxygen (O) atom have?

A.
lemon juice, distilled water, milk of magnesia

B.
distilled water, milk of magnesia, lemon juice

C.
lemon juice, milk of magnesia, distilled water

D.
milk of magnesia, distilled water, lemon juice

The question about valence electrons has nothing to do with the given answer choices.

An oxygen (O) atom has 6 valence electrons.

The question regarding the number of valence electrons an oxygen (O) atom has is unrelated to the possible answer choices provided. However, an oxygen (O) atom has 6 valence electrons.

To determine the number of valence electrons in an oxygen (O) atom, we need to look at its position in the periodic table. Oxygen is in Group 16, also known as Group VIA or Group 6A. The group number represents the number of valence electrons in the outermost energy level of an atom.

In this case, oxygen is in Group 16, so it has 6 valence electrons.

Therefore, the correct answer to the question is:

A. 6
