a) Write the electron configuration of the above atoms and the electron distribution in the outermost shell (s/p).
b) Determine their positions (period, group) in the periodic table of chemical elements, in order of decreasing atomic radius, increasing first ionization energy, decreasing electronegativity, decreasing metallic character, increasing non-metallic character from left to right?
c) Show the formation of ions from the above atoms.
d) Show the formation of ions from the following substances:
MgO, N2, F2, O2, K2O, Na2O, Al2O3, Na3N, K3S.
e) Write the formulas of the highest oxides and hydroxides of these elements.
f) Compare the acidic properties of acidic substances: NH3, CaCl2, KCl, CH4, CO2, H2O, KCl, Na2O, CaCl2. What substances consist of ionic bonds, covalent bonds?
Question 2: Give the following substances: (NH4)2SO4, (NH4)Cl. What substances consist of ionic bonds, covalent bonds?
