Question
Number 2 only
d. n=3 m = 1 m; = +½ Corrected value: 2. Without looking at the periodic table write the generic valence electron configuration for the first three periods of group 4A (14). 3. Give the symbol for the ion that would be formed if cadmium (Cd) gained 2 electrons: Explain briefly why the answer for this question cannot be Sn2. 4. Discuss the trend in atomic radius across a period. Explain why the general trend is that radius increases across the period from left to right, but in the d-block (transition metals) the atomic radius stays relatively constant. 5. You and a friend went out for Silas and Maddy's ice cream and are enjoying your treat outside. A pedestrian, who is COVID positive, passes by you (not wearing a mask) and sneezes in your direction. T droplets from their uncovered sneeze travel at a velocity of 35.0 m/s ± 1%, what is the uncertainty in position of the coronavirus from their sneeze if the virus mass is 2.14 × 10-14 g?
