How many electrons in F might be important for chemistry?
Fluorine has 9 electrons, and the most important electrons for its chemistry are those in its outermost energy level, which is the second energy level. Fluorine commonly gains one electron to achieve a full outer shell, giving it a stable octet arrangement.
Describe Why a stairway is a good model for energy levels in an atom?
A stairway is a good model for the energy levels in an atom because there is a 'main floor' ( the nucleus ) and steps ( the energy levels ). The nucleus is the start of the stairway of the energy levels, and the other energy levels go off of the nucleus. The first energy level can hold 2 electrons, the second energy level can hold 8. The third energy level can hold 18, and the fourth energy level can hold 32 electrons. In order for an element to be as stable as a noble gas, the outermost energy level has to be full, so sometimes an atom will gain or lose electrons to fill it's outer energy level. Other times it might share electrons with other atoms, so that they don't have to gain or lose a lot of electrons. An example of this would be H2O ( water ). There is one oxygen atom with two hydrogen atoms connected to it, and sharing their electrons with each other.
Are the starting products of photosynthesis?
You might mean the reactants, the reactants for photosynthesis are 6CO2 + 6H2O+ light energy. The products from these reactants are Oxygen, Glucose. Photosynthesis: 6CO2+6H2O+light energy--->6O2+C6H12O6.
In an ecological pyramid what information might be displayed about each tropic level?
In an ecological pyramid, each trophic level typically displays information about the biomass, energy, or number of organisms present at that level. The base level represents producers, usually showing the highest biomass and energy, while successive levels—herbivores and then carnivores—display decreasing amounts of biomass and energy due to energy loss through metabolic processes. Additionally, the pyramid may illustrate the flow of energy, highlighting the inefficiency of energy transfer between levels, often depicted as only about 10% energy transfer from one level to the next.
Why do we need oxygen?
The main purpose of oxygen in humans and other aerobic organisms is to allow the body to make energy. Energy is needed for a host of processes in the body such as growth, repair, movement, nerve conduction, etc., and can be gained from numerous sources, like carbohydrates, fats, and amino acids. However, for the body to use this energy, it must be oxidized. A molecule that is undergoing oxidation loses electrons, which store the electric and kinetic energy that the human body will use once absorbed. What this means is that when people breathe in oxygen, they can activate the latent energy that might have consumed before.

How many covalent bonds are required to connect to oxygen atoms together?
Two oxygen atoms connect via a double covalent bond, sharing a total of four electrons (two from each atom). This bond allows the oxygen atoms to achieve a stable electron configuration by filling their outermost energy level with eight electrons.
Why would oxygen level be low in infant?
The oxygen level for an infant can be low if they are having breathing problems. They should be checked by a doctor as soon as possible.
When an electron drops from a higher energy level to a lower energy level is it taken from the environment?
No, when an electron drops from a higher energy level to a lower energy level within an atom, the energy released in the form of a photon is given off by the electron itself, not taken from the environment. This process is known as emission.

What is most important element for respiration?
carbon oxygen hydrogen nitrogen
How might damaged alveoli affect the oxygen level in the blood?
Damaged alveoli can reduce the surface area available for gas exchange, including oxygen uptake. This can lead to decreased oxygen diffusion into the bloodstream, resulting in lower oxygen levels in the blood.
What might a person use as a source of chemical energy?
The most common form of chemical energy is from coal and petrochemicals like diesel. It is combined with oxygen at height temperatures to create heat energy or kenetic energy and secondly, electrical energy.
Give two reasons why it is better for human muscle cells to produce energy through aerobic respiration than through anaerobic respiration?
Aerobic means "with oxygen" and anaerobic means "without oxygen." Cells produce energy at a might higher and faster rate with oxygen than without.
What does oxygen have?
The atmosphere and particles of the evaporating water mixes in with the particles use to make oxygen what we all now oxygen. THIS IS MY SUGGESTION. ( I MIGHT BE WRONG AND I MIGHT BE RIGHT ).
What is the raw material of photosynthesis?
You might mean the reactants, the reactants for photosynthesis are 6CO2 + 6H2O+ light energy. The products from these reactants are Oxygen, Glucose. Photosynthesis: 6CO2+6H2O+light energy--->6O2+C6H12O6.
