7 How Are Electron Configuration and place within the Periodic desk comparable? 2. sixty one 2. sixty two resolution precise or fake. (a) parts within the comparable column of the Periodic desk have a similar outer-shell electron configuration. (b) All team 1A parts have one electron of their valence shell. (c) All team 6A parts have six electrons of their valence shell. (d) All workforce 8A parts have 8 electrons of their valence shell. (e) interval 1 of the Periodic desk has one point, interval 2 has parts, interval three has 3 parts, and so on. (f) interval 2 effects from filling the 2s and 2p orbitals, and as a result, there are 8 parts in interval 2. (g) interval three effects from filling the 3s, 3p, and 3d orbitals, and accordingly, there are 9 parts in interval three. (h) The main-group components are s block and p block components. Why do the weather in column 1A of the Periodic desk (the alkali metals) have comparable yet now not exact homes? part 2. eight what's a Periodic estate? 2. sixty three resolution precise or fake. (a) Ionization power is the power required to take away the main loosely held electron from an atom within the gasoline section. (b) while an atom loses an electron, it turns into a absolutely charged ion. (c) Ionization strength is a periodic estate simply because ground-state electron configuration is a periodic estate. (d) Ionization power usually raises going from left to correct throughout a interval of the Periodic desk. 2. sixty six 2. sixty seven 2. sixty eight sixty five (e) Ionization power normally raises in going from most sensible to backside inside a column within the Periodic desk. (f) The signal of an ionization power is usually optimistic; the method is often endothermic. give some thought to the weather B, C, and N. utilizing purely the Periodic desk, are expecting which of those 3 parts has: (a) the most important atomic radius. (b) the smallest atomic radius. (c) the most important ionization power. (d) the smallest ionization strength. Account for the next observations. (a) The atomic radius of an anion is often higher than that of the atom from which it really is derived. Examples: Cl ninety nine pm and Cl2 181 pm; O seventy three pm and O22 a hundred and forty pm. (b) The atomic radius of a cation is usually smaller than that of the atom from which it truly is derived. Examples: Li 152 pm and Li1 seventy six pm; Na 156 pm and Na1 ninety eight pm. utilizing in basic terms the Periodic desk, manage the weather in each one set so as of accelerating ionization strength: (a) Li, Na, okay (b) C, N, Ne (c) O, C, F (d) Br, Cl, F Account for the truth that the 1st ionization power of oxygen is lower than that of nitrogen. each atom other than hydrogen has a sequence of ionization energies (IE) simply because they've got a couple of electron that may be got rid of. Following are the 1st 3 ionization energies for magnesium: Mg 1 g 2 h Mg1 1 g 2 1 e2 1 g 2 Mg1 1 g 2 h Mg21 1 g 2 1 e2 1 g 2 Mg21 1 g 2 h Mg31 1 g 2 1 e2 1 g 2 IE1 five 738 kJ/mol IE2 five 1450 kJ/mol IE3 five 7734 kJ/mol (a) Write the ground-state electron configuration for Mg, Mg 1 , Mg21, and Mg31. (b) Account for the massive elevate in ionization strength for the elimination of the 3rd electron in comparison with the ionization energies for elimination of the 1st and moment electrons.
