15. Compared with the atomic radius of oxygen (z-8), the atomic radius of sulfur

Question

15. Compared with the atomic radius of oxygen (z-8), the atomic radius of sulfur (z 16) is a. larger because the n quantum number increases. b. larger because the quantum number increases. smaller because the atomic number (nuclear charge) increases d. about the same because in both cases, the nuclear charge equals the number of electrons. e. smaller because the n quantum number increases. 16. Which of the following occurs only in discrete (quantized) increments? a. money b. the speed a car drives on the interstate c. time d. the altitude that an airplane flies e, the level of water in a sink

Explanation / Answer

15)
from z=8 to z=16, an extra shell is being added. This is the reason radius increases as we go down a group in periodic table
Answer:
a. larger because the n quantum number increases

16)
Answer: a money
rest all are continuous and cannot be quantized
