electron transfers?

Question

i dont understand electron transfers!

do any of these have a full complement of electrons?-
-Ag+
-Ca+2
-Cu
Zn+2

are any of them missing its outer ring of electrons?

Answer 1

Most atoms try to gain or lose electrons in such a way that they wnd up having 8 electrons in their outermost shell. For example, Calcium (Ca) had 2 electrons in its outermost shell, so it will lose those two electrons so that the shell that was originally second to theoutermost has now become the outermost shell with 8 electrons... and because Calcium has lost 2 electrons in the process, it now has a double positive charge: Ca2+

Hope this will help you get started!

Answer 2

Each of the atoms you listed have either more or less than a number of electrons equal to the number of the protons (a condition needed to make the atom neutral) except Cu (ignoring the little - sign in front of all but Zn). So all but Cu have 8 electrons in their outer ring.

So to simply, a full compliment is 8 electrons in the outer shell. Ag, Ca, and Zn have lost electrons to accomplish this, Cu is neutral but will need to lose an electron or 2.

They will now need to neutralize with a negative ion-thus the compound forms.

Answer 3

this might properly be a case of electrostatic cost. some factors grow to be negatively charged while rubbed others grow to be truthfully charged - it rather is merely the way it quite is. needless to say there's a sources of the textile that facilitates electrons to be quite faraway from the exterior ; it rather is, there's a smaller stress of charm for the electrons interior the exterior shape - so dropping electrons makes it much less damaging - so it is going to become truthfully charged.
