What is the same about the electronic structures of lithium and sodium?

Biology

Sedaia [141]3 years ago

Answer:

Sodium and lithium are in the same group of the periodic table; this is because they both have the same number of electrons in their outer shell (1 as indicted by the group number). this commonality is the reason they have similar chemical properties. As we go down the group however, the electronic structure of atoms of an element changes as that there are a increasing numbers of ‘shells’.

Electron ‘shells’ are filled according to ruled of quantum mechanics however to simplify things in this case the first shell can fit 2 electron, the second 8, and the third shell 8. Lithium has 3 electrons, hence it the first shell is filled, and 1 electron occupies the second shell. Whilst Sodium has 11 electrons, hence its first two shells are filled and the third shell is occupied by one electron.

To expand on this question, the duet/octet rule is a rule in quantum mechanics that observes that main group elements tend to be stable with a full outer shell.

This explains why sodium and lithium is found in the form of Li+ and Na+ ions in nature.

what will happen if one of the levels in the biological organization will not perform its function properly?​
Sedaia [141]

Answer:

It would affect the functionality of the other levels including the organism

Explanation:

The level of biological organization is a hierarchical step consisting of how a multicellular organism forms. According to this level of organization, CELLS are the simplest unit of life and the collection of cells with a similar function is termed TISSUE. Tissues form ORGANS, organs form ORGAN SYSTEMS and finally, a collection of all the systems in the body forms the ORGANISM.

Based on this, one would observe that each level is related to the next in such a way that one forms from the other. Hence, if one of the levels in the biological organization will not perform its function properly, the other levels will be affected. For example, if the kidney cells do not perform it's function, it would affect the functionality of the kidney tissues, kidney organ, the excretory system, and the organism at large.

What is the function of monomers and polymers in protein
IRINA_888 [86]

Answer:

They are the monomers of the proteins.

Explanation:

When hundreds or thousands of amino acids join together, they create proteins, which are then used for many tasks in organisms, such as doing work in cells, help with DNA replication, etc. So, the monomer will be the amino acids, and the polymer will be the proteins themselves.

"Which molecule controls the rate of pentose phosphate pathway?
kirza4 [7]

Answer:

Part 1:

Correct option is A: "NaDP+/NaDPH"

Part 2:

Correct option is F: "glucose 6-phosphate dehydrogenase"

Explanation:

Various levels of control are put in place to keep a check on the pathway. This is an example of one such control. This dehydrogenase enzyme is responsible to control the rate of reaction and it is stimulated by NADP+ while it is inhibited by NaDPH. The oxidative reaction is under the influence of the NaDP+/NaDPH concentration, which is catalyzed by glucose 6-phosphate dehydrogenase.

Hope that answers the question, have a great day!
