IVA: nonmetal/other metals VIIA:halogens VIII: Nobel Gases
The octet rule states that atoms tend to form compounds in ways that give them eight valence electrons and thus the electron configuration of a noble gas
Answer:
Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the Sun.

Answer:
<em>B. Female Merrick sea turtles begin returning to Bakerâs Beach to lay their eggs when they are ten years old.</em>
Explanation:
Firstly, There was an oil spill five years ago-no eggs hatched.
Now, the number of females coming back to the lay eggs has increased somewhat since the last five years.
The theory is that a period of 5 years is sufficient to assess effect on population.
If the breeding cycle has been found to be ten years long, then the impact of the oil spill on the population (as observed by the number of females returning to lay eggs) will only be perceived in the 10th year.
It undermines the argument that the oil spills don't impact the public.
