1c) Gallium has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p1: lowest energy level is the one which is nearest to the atom’s nucleus and that is s subshell of quantum shell 1. Highest energy level is in quantum shell 4 and has p subshell with only 1 electron.
Electricity
Metals are good conductor of electricity. They differ in electron (negatively charged particle) arrangement- few metals carry loosely bound electrons in their outermost shell.
