Douglasite is a mineral with the formula 2KCl. FeCl2.2H20 Calculate the mass percentage of douglasite in 445.0 mg ore if 37.20 ml of a 0.1000 M AgNO3 solution is required to precipitate all cl- as agcl

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above
