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

Biology
2 answers:
Lerok [7]2 years ago
8 0

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, <em>all </em>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.

The three metabolic pathways that make up aerobic respiration are really all parts of one larger pathway because the products of
Anuta_ua [19.1K]

Answer

          The three metabolic pathways that make up aerobic respiration are really all parts of one larger pathway because the products of early pathways (like NADH) become <u>utilize</u> in the last one.

Explanation

         Aerobic respiration is that type of respiration in which glucose molecule is broken down into CO2 and H2O in the presence of oxygen and 36 or 38 ATP molecules are produced.

Aerobic respiration complete in four main steps:

1. Glycolysis

                  In this step glucose is broken down into 2 molecules of pyruvate acid along with the production of 2 ATP molecules and 2NADH.

2. Oxidation of pyruvate

                In this step pyruvate are oxidized in the presence of co-enzyme A to become Acetyl Co-enzyme A.  Again 2NADH are formed in this step.

3. Kreb Cycle

            It occus in mitochondria. Here acetyle coenzyme A enter Carbon fixation, reduction and regeneration phase. In this cycle 6 NADH, 2FADH2 and 2ATP are formed.

4. Electron transport chain

            All NADH that are produced in above steps get oxidize and help in the production of ATP along with the release of electron and proton that help in the formation of water.

Why is it important to use a weakened virus in a vaccine?
PolarNik [594]

If you used a full active virus, that defeats the point of a vaccine. You will trigger your immune response, but since you would just be injecting the virus, it will make you sick, and your body will be less effective at fighting the pathogens.

Viruses in vaccines are weakened, so they essentially will not "fight" back. They most importantly just contains the antigen markers so the body can trigger the immune response, quickly eradicate the pathogen, and build up the memory cells to that virus.

Injecting a virus that is not weak will just be the same thing as if you got the virus, you will likely get sick.

Which of the following nations is not a republic?
garik1379 [7]

Answer:

The United Kingdom.

Although the direct reduction of CoQ to CoQH2 is thermodynamically possible, this reaction is not a direct part of the electron
Nady [450]

Answer:

This electron handoff from NADH to FMN, as opposed to direct reduction of CoQ by NADH, a critical component of the electron transport chain is important for Signaling Transduction and Metabolomics

Explanation:

The NADH-CoQ reductase reaction is catalyzed by Complex I. In this course of activity, following events takes place-  

a) FNM (NADH dehydrogenase flavoprotein) is reduced by the NADH  to FMNH2 through following reactions –  

NADH+H++E-FMN↔NAD++E-FMNH2

b) In the next phase coenzyme Q  receives electron from FMNH2  through the the iron–sulfur centers of the NADH-CoQ reductase

c) The iron atom undergoes oxidation–reduction cycles to conserve  mitochondrial protein  as lataxin and hence transport protons from the matrix to the intermembranal space thereby Signaling Transduction and Metabolomics

beks73 [17]
The maxillary bones and mandible are part of A. the facial bones.

In fact, maxillary and mandible are primary bones of the face which also includes, nasal bones, zygoma, and frontal bone.

Both are found in the jaw area. The mandible bone is located near the lower jaw, while the maxilla is found near the nasal portion of the face.
