In the image below we see, from left to right, the Pixel (5-inch), Nexus 5X (5.2-inch), Pixel XL (5.5-inch), and the Nexus 6P (5.7-inch). Compared to the Nexus devices, itâs quite impressive how much Google has trimmed down the overall size of these smartphones.
An atom of calcium has 2 valence electrons and an atom of sulfur has 6 valence electrons how many lone pairs of electrons are present in the lewis structure of calcium sulfur. 1. Follow.
Sulfate is a polyatomic SO4 ^2-. S is number 16 the rule is the 1st orbital can only hold 2 electrons ,then the rest can hold a max of 8 so the last orbital is the third for sulfur and it has the remaining 6 electrons. Also. So since sulfur S is in group 16 it has 6 valence electrons.
