shows the electronic configurations of five atoms, D, E, F, G and H. D E F G H Answer the questions about these electronic configurations. Each electronic configuration may be used once, more than once or not at all. State which electronic configuration, D, E, F, G or H, represents: an atom of an element in Group VI of the Periodic Table an atom that forms an ion that gives a lilac colour in a flame test an atom of a monatomic gas an atom of an element that is used in the treatment of the domestic water supply to remove tastes and odours an atom that forms a stable ion by losing two electrons. Deduce the number of protons and neutrons in the chromium atom shown. 24Cr number of protons number of neutrons
