Q. Why are atoms of the noble gases generally inert?
At the top of the noble gases is little helium (He), with a shell that is full with only two electrons. The fact that their outer shells are full means they are quite happy and don’t need to react with other elements. In fact, they rarely combine with other elements. That non-reactivity is why they are called inert.

| Chlorine | 3.16 |
Q. Which of these compounds is most likely to contain an ionic bond so2 cacl2 h2 ch4?
Explanation: The compound most likely to contain an ionic bond is CaCl₂ because it is the only specie with a metal and non-metal.
Q. Which of these elements has the smallest atomic radius Sol?
Helium
Q. Which element has largest atomic radius?
francium
Q. Which of the following atoms has the largest atomic radius?
So Cesium has the largest atomic radius among the given elements.
Q. What is carbon’s atomic radius?
170 pm
Q. Which element has the largest atomic radius in Group 1?
the radius of an atom of the element increases from 134 pm to 225 pm….(A) Trends in the Atomic Radius of Group 1 (IA, Alkali Metals) Elements.
| Element | lithium |
|---|---|
| Atomic Number (Z) | 3 |
| Symbol | Li |
| Simple Electron Configuration | 2,1 |
| No. Energy Levels (electron shells) | 2 |
Q. Why does boiling point increase down Group 1?
Trends in melting and boiling points When any of the Group 1 metals is melted, the metallic bond is weakened enough for the atoms to move more freely, and is broken completely when the boiling point is reached. The decrease in melting and boiling points reflects the decrease in the strength of each metallic bond.
Q. What noble gas has the largest atomic radius?
Q. Which gas is highest in our environment?
Atmospheric levels of carbon dioxide—the most dangerous and prevalent greenhouse gas—are at the highest levels ever recorded.
Q. Is Xenon the rarest gas?
There are two billion tonnes of xenon in the atmosphere but it is still one of the rarest elements on Earth. There is much less of it than the other noble gases – which explains why it is 50 times more expensive than neon.
Q. What does the name xenon mean?
stranger
