What are the noble gases?A.Elements with two valence electronsB.Elements with seven valence electronsC.Elements with one valence electronD.Elements with two or eight valence electrons

44. Which statement does not describe noble gases?1 pointThe more massive noble gases react with other elements.They belong to group VIIIA or 18.They contain at least one metalloid.He, Ne, Ar, Kr, Xe and Rn are included in the group.

The noble gases include helium, neon, argon, krypton, radon and xenon. Identify the time period when most of the noble gases were discovered.

The elements in Group 18 are known as noble gases.In terms of their electron configurations, explain what the noble gases all have in common.

What group of the periodic table are the noble gases found in?Group 2Group 0Group 1Group 72Which of the following is not a property of the noble gases?They are colourlessThey have high boiling pointsThey exist as single atomsThey do not form molecules3Which is the best explanation for why the noble gases are unreactive?They all have low boiling pointsThey are all gasesThey all have full outer electron shellsThey are all large atoms4Which noble gas has the following electronic structure: 2, 8, 8?HeliumKryptonNeonArgon5The boiling point of helium is -269°C, while that of argon is -185.8° Predict the boiling point of neon:-275°C-246°C-269°C-176°C
