Formulae And Acids (Completed)

Question 1

What happens with metal atoms when they react ionically and why

Answer 1

They lose electrons to form positive ions (cations).
They do this In order to achieve the same electron structure as the nearest noble gas, as this makes them stable

Question 2

What happens when atoms of non-metals react ionically and why

Answer 2

They gain electrons to form negative ions (anions)
They do this in order to achieve the same electron structure as the nearest noble gas, therefore be stable.
