I'am getting really confused with exchange rates. Like when a currency appreciates, what does that mean? Are the foreign goods more expensive or cheaper? How about when it depreciates? It would be helpful if somebody gave me a quick lesson on this. Thanks...

which element will have the greater metallic character? Cs or Sr Ge or In Al or K Sr or Rb

which element would have 2 electrons and +1 charge which element would have 18 electrons and +3 charge.

Arrange the following pure solid elements in order of increasing electrical conductivity: C, Hg, As

yes, hydrogen (H)

Reworded: Enter the symbol of the element which would have 18 electrons and +3 charge and the element with 2 electrons and +1 charge

thanks so much!
