Using complete subshell notation (1s2 2s2 2p6, and so forth), predict the electron configurations of the following ions. Nitride anion (N-3)

Two sets of ionizations are shown in the tables below. Complete the tables by ordering each set of ionizations by increasing amount of energy required. In other words, for each set choose "1" next to the ionization that would require the least energy, "2" next to the ionization that would require the next least energy, and so on. ionization + Pb → Pb + e He + ► F + e F→>> + - → He + e ? ? energy required ? V ionization + Br Br + e → + Sn Sn +e + He → He + e energy required ✓ ? 1 (least) 2 3 (most)

Which of the following ionic compounds did you find to be diamagnetic? sodium chloride magnesium chloride aluminum chloride aluminum oxide iron(III) chloride cobalt(II) chloride copper(II) oxide

Coal is a form of carbon that serves as fuel to generate heat or electricity. Incomplete combustion of carbon in coal (at low oxygen concentrations) leads to carbon monoxide (2 C + O2 --> 2 CO). Complete combustion of carbon results in carbon dioxide (C + O2 --> CO2). Using this information and the periodic table of the elements, draw a schematic of the reactions between oxygen and carbon. Show the electron shells of all participating atoms and molecules and indicate the number of electrons in each shell including the shared electrons in molecules.

Predict the electron configuration of each of the following atoms: C Ca2+ N
