Question

EXAM 5 1. Draw the Lewis dot diagram for the carbon atom. 2. Draw the Lewis dot diagram for the O2 ion. 6+2 8 3. Give the electron configuration (1s22s ) for the S-2 ion. 4. Which has the larger radius. S or s2? 5. Which has the larger radius, Ca or Ca2? 6. Arrange in order of increasing ionic radius (smallest to largest): Cr. K+1S2 7 Give the Lewis dot diagram for the covalent compound SOCl2 . 8. Arrange in order of lowest to highest electronegativity: As, Ge, P 9 Given these electronegativities (Si 1.8, 0 3.5, c 2.5, Br 2.8, As 2.0) which of these bonds is least polar? a) Si-o b) C- Br c) As - Br 0 Write 2 resonance descriptions for H

Explanation / Answer

1) :C:

3) 1s2 2s2 2p6 3s2 3p6

4) S2- will have larger radius then S because adding of electron increases the shielding effect which ultimately increases the radius due to the increase in shielding between atomic nucleus and outermost electron

5) Ca will have larger radius because loss of electron will ultimately increase the positive charge and attraction between outer most electron and nucleus will increase in Ca2+
