The first layer has two, since the maximum amount of electrons you may have in layer one are two, after the first layer you may have a maximum of eight electrons per layer, so layer one has two, layer two has eight, and layer 3 has a maximum of 18. To find the maximum number of electrons each layer can have do the equation 2(n2) n=number of layers

How many valence elections are transferred from the calcium atom to iodine in the formation of the compound calcium iodine?
One calcium atom will transfer one of each of its two valence electrons to one each of two iodine atoms. In the process, the calcium atom becomes a calcium ion with a 2+ charge, and each iodine atom becomes an iodide ion with a 1- charge. The opposite charges between the iodide and calcium ions form an electrostatic attraction called an ionic bond, forming the ionic compound calcium iodide. Ca + I2 ---> I- + Ca2+ + I- ---> CaI2
