Answer: the electrons i.e their valence electron
Explanation: valence electron is the number of electron in the outermost shell of an atom. Infact it is the combining power of an element. The valence electron gives us a better understanding of how an element will react with other elements. This is the reason why elements with the same number of valence electron(s) are grouped together telling us that they exhibit similar chemical properties

Answer:Do you think the climate change has only to do with human society or is it also occuring "naturally"?
I was in Germany on december of last year (2011) and I was surprised because it didn´t snow. I read about the melting of the principal glacier and it will raise the ocean water levels. There are people that blame only human being for the climate changes but I wish to know how much we are responsible for that.
Climate Change
Explanation:
Answer:
When the average kinetic energy of the molecules goes up (a rise in temperature), the average speed of the molecules increases. And lower average kinetic energy of the molecules means they have lower speed. When heat (energy) goes into a substance one of two things can happen:
Explanation:
If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. ... If the gas volume is decreased, the container wall area decreases and the molecule-wall collision frequency increases, both of which increase the pressure exerted by the gas (Figure 1).
