Answer:
We can predict or comment about reactivity of elements by taking into consideration their electronic configuration that imparts stability or un-stability to an atom.
Explanation:
Reactivity : It refers to the affinity of a substance to combine with other substance .
Elements are mainly of two types :
In terms of metals or non metals it can be defined as tendency to loose or gain electrons .
- On the basis of it ,we can easily make out or comment about the reactivity of element (metal or non metal ) .Like ,if an element has completely filled outermost shell or we can say have stable electronic configuration then it is already stable .Therefore , it won't react with any other element .
- But, if its outer shell isn't complete then in order to attain stability it will combine or react with other .Hence , we can say it will be quite reactive .

<span>If guppies are small fish with famously high fecundity, the prediction that I can make about survivorship is that they can adapt very easily to their surroundings and the environment they are living in. Their high fecundity is the ability for the higher reproductive level or rate. </span>
In bone growth, the medullary cavity is enlarged because of the activity of osteoclasts. These are cells working to break down bone, resorbing old bones which will line in the medullary cavity. The cavity is also enlarge as the cells contribute to the increase in length and diameter of a growing bone.
