Which element has seven energy levels the only one valence electron

Biology
1 answer:
denpristay [2]3 years ago
5 0

Answer:

Your answer is chlorine.

Explanation:

Valence electrons help in predicting chemical reactions. For example, since hydrogen (H) is in group 1, it has 1 electron in its outer energy level. Chlorine (Cl), which is in group 17, has 7 electrons in its outer energy level and is one electron short of having a "full" outermost energy level.

I hope that helped. :)

I have snap chat if you need it.

<h3><u>Answer;</u></h3>

Divergent evolution;

<h3><u>Explanation;</u></h3>
  • Divergent evolution is the process of two or more related species becoming more and more dissimilar. In this type of evolution groups of species from the same common ancestor evolve and accumulate differences, resulting in the formation of new species.
  • For example; <em><u>The red fox and the kit fox. The red fox and the kit fox both have a common ancestor but have gone through the process of divergent evolution. It has adapted to its mixed farmland and forest environment. Its red color helps it to blend in with the trees.  </u></em>
  • <em><u>The kit fox is sandy in appearance because it lives in the desert. It also has larger ears than the red fox and its larger ears help the fox release excess body heat in the desert.</u></em>

the graph in figure 5-7 shows the changes in population of bass in a lake. Describe the trend in population growth from 1950 to
Rainbow [258]

In exponential growth, the growth rate of population per capita remains the same in spite of the size of the population, thus, resulting in the population to grow faster and faster as it gets bigger. However, in nature, the populations may grow exponentially for certain time duration, and they eventually get restricted due to limited availability of resources.  

In the graph, it is evident that from 1950 to 1990 there is exponential growth, signifying that the fish exhibited almost optimal conditions of living. However, in 1990 the population started to decline steadily, demonstrating an extreme lack of resources or enhancement in predatory species.

a type of pollution in which the source of pollution is NOT easily identifiable is called ______ source pollution.
arsen [322]

your answer is Nonpoint source pollution because this occurs due to a spreading of contaminants into a larger area and the actual source of the pollution can not be defined.

some examples are air, water and soil pollution. Mainly from vehicles the air is being polluted and we can not trace it.

same happens in case of water and soil many hospitals, factories, labs and even homes discard some pollutants and we can't find a single source.

if the source is only single place like a particular hospital or handicraft factory than we can call it as a point source pollution.
