How many valence electrons do noble gases typically have?

• A. 2
• B. 4
• C. 6
• D. 8

Answer: (D)

Verified step by step guidance

1. Recall that valence electrons are the electrons in the outermost shell of an atom, which determine its chemical properties and reactivity.
2. Noble gases are elements found in Group 18 of the periodic table, known for their stability and low reactivity.
3. Most noble gases have a full outer electron shell, which means their valence shell is completely filled with electrons.
4. For noble gases (except helium), the valence shell contains 8 electrons, following the octet rule, which explains their chemical inertness.
5. Therefore, the typical number of valence electrons for noble gases is 8.
