Hydrogen atom = 1 proton 1 electron Hydrogen's 1 electron occupies the lowest energy level, 1s orbital. The atom is therefore in its "ground state". When a photon of correct frequency "collides" with a electron in hydrogen's 1s orbital the energy contained in the photon is transferred to the electron. The electron then gets added energy, so it is at a higher energy state. When it reaches this higher energy state the electron jumps to the next energy level and there it starts its new orbit. Hydrogen atom is now "excited" For any other atoms it is the same thing because all atoms can undergo excitation. The only difference between hydrogen's 1 electron and other atom's many electrons is WHICH ELECTRON will be "excited"

the vast majority of the volume of an atom is filled with absolutely nothing there is a central heavy nucleus and "whizzing" round it are a number of much lighter much smaller electrons. from the outermost reaches of the electrons orbits to the centre of the nucleus there is an awful lot of "nothing" an analogy is to consider the earth we are a heavy central body - compare us to the nucleus of an atom whizzing round us are various satellites - the moon and many small artificial ones we have put up - compare them to the electrons in between and making up by far the bulk of the volume occupied by the "earth and its satellites" is a lot of nothing - just like in an atom
The proton is pumped from the stroma across the thylakoid membrane, into the thylakoid lumen. This movement of protons creates a proton gradient that is used to generate ATP through chemiosmosis during photosynthesis.
An electron reaches a state of zero energy when it is at rest or in its ground state.
An electron reaches zero energy when it is at rest or in a state of lowest energy level, typically in an atom's ground state.
The temperature in cells is not high enough. Each of the redox reactions in the electron transport chain are catalyzed by an enzyme. NADH dehydrogenase transfers electrons from NADH to ubiquinone, and cytochrome c oxidase transfers electrons from cytochrome c to oxygen. So there is no enzyme to pass the electrons directly from NADH to oxygen.

The outer orbital, or valence shell, around the nucleus of an atom possess what are commonly called valence shell electrons. They represent the electrons available to share with another atom for the formation of covalent bonds between atoms. For Na, or sodium, in its standard atomic state there is only 1 valence shell electron. This number increases as you go to the right across the periodic table until the number of valence shell electrons reaches 8. This is noted by the Column number (i.e. I, II, III, etc.). Carbon has four, Nitrogen has five, Oxygen has 6, and Fluorine has 7. Xenon, Argon and the other 8th column elements are called the noble gases and they all have 8 valence electrons.
Anywhere there is a wifi signal you have the password for. 3G models can get internet anywhere their carrier's cell signal reaches.
The collapsing Sun's core will halt when the core reaches a state of equilibrium where the inward force of gravity is balanced by the outward force of electron degeneracy pressure. This results in the formation of a white dwarf, the core remnant of the Sun after it exhausts its nuclear fuel.
Hydrogen atom = 1 proton 1 electron Hydrogen's 1 electron occupies the lowest energy level, 1s orbital. The atom is therefore in its "ground state". When a photon of correct frequency "collides" with a electron in hydrogen's 1s orbital the energy contained in the photon is transferred to the electron. The electron then gets added energy, so it is at a higher energy state. When it reaches this higher energy state the electron jumps to the next energy level and there it starts its new orbit.

A free electron at rest in an electric field will experience a force due to the field and will accelerate in the direction of the electric field. The electron will gain kinetic energy and start moving in the direction of the force until it reaches a velocity where the force due to the field is balanced by other forces acting on the electron.
Energy is either absorbed or released. If the electron goes from a high energy orbital to a lower energy one, a photon is emitted. When a photon is absorbed, the electron goes from low energy to high.
