If an atom has 15 electrons, how many electrons are in the n=1 energy level?
IRISSAK [1]

Answer:

In the n=1 energy level, the atom has 2 electrons

Explanation:

Electrons orbit the nucleus of an atom in multiple rings (energy levels). The first ring of the electron can only hold 2 electrons. After that, electrons are added to the second ring. Excluding the first ring, all other rings can hold a maximum of 8 electrons.

For example, Oxygen is an atom with 6 electrons. The first energy level contains 2 electrons, and the second energy level contains 4 electrons. The second energy level has room for up to 4 more electrons.

In your example of an atom with 15 electrons, there would be 2 electrons in the first ring, 8 electrons in the second ring, and 5 electrons in the third and final ring.

To summarize, all atoms have a first energy level containing 2 electrons, and all other energy levels can contain 8 electrons. This is true no matter the number of electrons.

Answer:

Corpus callosum

Explanation:

Corpus callosum is the red part of the brain that has a “C” shape. The corpus callosum, which is made up of over 200 million of neural fibers, links both hemispheres of the brain (the left and right brain) together, which allows for coordination and complex communication between both in order for the brain to function properly.

This structure usually starts forming about 12 weeks after conception of a child, and continues to develop up to about 12 years of age of the child.  

The main function of the corpus callosum is the ensuring of uninterrupted flow of information, and the integration of complex information and tasks such as motor, sensory and cognitive functions between both hemispheres of the brain.
