The numbers listed represent the number of electrons in the first, second, and third energy levels, respectively. On this basis,
yulyashka [42]

Answer:

D

Explanation:

This is because one of its orbital shells is not filled – the one with 1 electron. This atom will, therefore, want to lose this electron – it takes less energy to do this than gain 7 electrons -- to achieve stable electron configuration. This makes this atom very reactive in a chemical reaction.  Usually orbital shells of atoms begin with an S orbital shell that is filled with 2 electrons then P (x,y,z) orbital shells filled with 6 electrons total. There are also higher energy f and d orbitals that each take a maximum 10 and 14 electrons respectively. An atom is stable if its orbitals are fully filled.

Which event is an example of genetic drift? An earthquake kills 90 percent of the green beetles in a population of green, black,
den301095 [7]
The answer is C. Genetic drift is the change of an allelic frequency due to random sampling in a population. When the brown and black bottles are preyed upon compared to the green bettles, their numbers in a population decrease. Therefore the next generations/offsprings of bettles population is more likely to be of green beetles since they will be more in the parent population. The allelic frequency of the allele for green bettles becomes higher than that of brown and black beetles. Eventually, after generations, the black and brown beetles may be eliminated from the population
