A sample of Cl 2 gas occupies a volume of 11.4 L at 3.50 atmospheres and 273K. When the Cl 2 is changed to STP conditions, what will be its volume? b) How many molecules of Cl 2 are there? (isothermal change)

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

a electronegativity decreases beacuse the size of nucleus is bigger.
