Answer:
3 Shells
Explanation:
2 electrons in shell one, 8 in shell two and only 1 in shell three.
Convection
Explanation:
Heat is a form of thermal energy borne as result of thermal energy. It is observed as temperature differences between places.
There are different types of heat transfer:
- Conduction
- Convection
- Radiation
Conduction is a heat transfer which involves the actual movement of the collision of the molecules of the medium.
Convection is a heat transfer in fluids by their movement from areas of higher to places of lower heat.
Radiation is heat transfer using electromagnetism and does not involve molecules of the medium
The process of heat transfer from ground to the air touching it is convection. It involves particles of the air.

Between 1.00 & 1.5 grams would be the normal amount
Ahh. The chain reaction.
.
You know when you are surfing the web, your parents tell you, or you surf the web, that you see some things like "STOP GLOBAL WARMING?"
.
Yep, I have, at least.
.
Well, let's see about the chain reaction...
.
You see, where does our energy come from?
.
Yes, windmills and solar cells...
.
but also nuclear and power plants, no?
.
The power plants emit carbon dioxide that contribute to global warming.
.
Now, cars do the same. One car may not seems like a lot of carbon dioxide...
.
.
But... this many cars multiplied by 9 trillion times 9 trillion and much more... is...

Well, you know the difference.
.
They contribute to global warming over a period of time, slowly, because they emit carbon monoxide/dioxide.
Being frozen, staying a liquid, becoming ice, and becoming a gas (steam)
