Sarah is learning about human-harnessed electricity as well as naturally-occurring electricity. sarah comes in contact with many forms of electricity each day. which is an example of sarah coming in contact with naturally-occurring electricity? a) sarah walks quickly across the carpet in socks and feels a small shock on her foot. b) sarah felt a small sting on her finger when she changed the light bulb on her lamp. c) sarah was lightly shocked when she inserted the plug of her lamp in the wall socket. d) sarah accidentally left her curling iron plugged in and burned her hand on the metal.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
