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 :

Metals and Non metals

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 .

Why do you think some bones, such as the humerus and femur, have rounded ends? Why do you think other bones, such as the vertebr

alekssr [168]

Answer:

1. Their rounded shape allow them to joint properly with other bones, permitting a softer, better motion.

2. Provide protection for specific organs and their shape provides a broad surface for the proper attachment of muscles.

Explanation:

The bone is a connective tissue composed of specialized cells, a mineral-salt matrix, and collagen fibers. The main functions of the bones are organ protection, structure, red and white blood cell production and support.

There are different types of bones:

Long
Short
Flat
Sesamoid
Irregular
Sutural

Some bones, such as the humerus and femur, are characterized by their rounded ends, also known as epiphyses (epiphysis - singular). The reason behind epiphyses is joint function. These bones are long bones, and their rounded shape allow them to ajoint properly with other bones, permitting a softer, better motion.

On the other hand, flat bones, such as vertebrae and carpals, provide protection for specific organs and their shape provides a broad surface for the proper attachment of muscles.
