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.
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.
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.
What is the outermost planet till march 1999?
In our solar system the outermost planet 'til March 1999 was considered the same as the outermost planet after March 1999 - it was Pluto. In 2006, the IAU reclassified Pluto as a minor or dwarf planet and no longer a true planet - this demotion meaning Neptune would thereafter be considered the outermost planet in our solar system. It is of course possible there is a planet out there not yet discovered, which is in solar orbit, and large enough, in which case its distance might qualify it as 'outermost'.
How can oxygen be efficient for space discovery?
Oxygen is used in the launch of space vehicles to make discoveries.

When an electron drops from a higher energy level to a lower energy level is it taken from the environment?
No, the energy released by electron might be taken by enviornment. Electron remains in the infuence of corresponding nuclei, in another energy level.

Can energy be in negative?
It might, depending on how you define it. Especially in the case of gravitational potential energy, the "zero level" or "base level" is arbitrary; you might define the base level as ground level, for instance. In that case, any object above ground level has a positive potential energy, and any object below ground level has a negative potential energy. Ultimately, what matters is not how much potential energy an object "really has" - it is really hard to define or ascertain this - rather, what matters is how much the energy CHANGES from one position to another. The case is similar with voltages, which are related to potential energy in an electric field.
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.
Plants do not use much energy and?
Actually, you might be shocked by this, but plants require small amounts of Oxygen. i am not sure why, or any of the details, but they do need oxygen.
What is chemical reaction of burning copper?
There isn't a reaction really. this is a flame test that shows the basic principle behind the likes of atomic adsorption spectroscopy and the like. What happens is, copper is heated over a Bunsen burner. in the actual atoms, the outermost electron/s in the outer energy level of the atom become excited due to energy from the flame. They jump to a higher energy level than before, and when they fall back down to the original energy level they emit a photon of light, which accounts for the colour change of the flame
What is most important element for respiration?
carbon oxygen hydrogen nitrogen
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 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.
Where is potential energy stored in airplanes?
That might refer to the fuel, which has chemical energy. Also, any object that is above a reference level (for instance, the ground level) has gravitational potential energy. That energy isn't stored in a specific place; it is related to the interaction between the two objects - in this case, the plane and the Earth.
