A hydrogen atom is in its n = 6 excited state.  what is the total enerrgy?
930815
i think there is a formula like 13.6/n^2.where n=state.find out for n=1 and n=6 states and the difference of these two energies will give u the answer u require.

The total number of protons in a water molecule is fixed. It has 10 protons.\nHowever, because there are many isotopes of hydrogen and oxygen, so the total number of neutrons in a water molecule is not fixed. For the water molecule formed by protium (no neutrons) and oxygen-16(eight neutrons), it has only 8 neutrons. For the water molecule formed by deuterium (one neutron) and oxygen-16, it has 9 neutrons. For the water molecule formed by tritium (two neutrons) and oxygen-16, it has 10 neutrons.

The sun is made of hydrogen.

The sun gives us light because of nuclear fusion-two atoms of Hydrogen are combining in huge quantities to form one atom of Helium. The mass of two atoms of Hydrogen are slightly more than one atom of Helium, which is mono atomic.The difference in this mass is converted to energy in the form of Heat and Light, rays of which don't need a medium to travel.

Nature is all about entropy or conservation of energy.  Stars of which Our Sun is one start their life as large balls of Hydrogen gas.  Due to the friction of the untold number of molecules  moving about, heat is developed- just like rubbing Your hands together.  The inside temperature of the Sun is about 2 million degrees.  It takes more energy to maintain 4 atoms of hydrogen than it does for one Helium.  With all the heat in the star's core it is possible for the hydrogens to form a helium by the process of nuclear fusion.  6 hydrogens take part in the reaction but two are recovered so the net result is 4h>1He.  This reaction results in the saving of 0.6% energy which works its way to the surface and radiates out into space.  Within the Sun it is estimated that about 745,000 tons of H are converted every second.  This number varies a bit when one reads the literature, but whatever the actual number is it is huge.

In a hydrogen atom, the energy of each level is given by:\n\nE=(-Z^2)(E0)/n^2\n\nwhere Z=the charge on the nucleus, E0=the energy of the ground state (the lowest level), n=an integer corresponding to the state (it equals 1 for the ground state.)\n\nTo find the energy emitted or absorbed, you simply subtract the energies between the two levels.\n\nI don't think you're likely to encounter any atoms more complicated than hydrogen or positive helium ions (which act like hydrogen). In any case, if you need the more general formula, don't be afraid to e-mail me. The above will work, by the way, for any atom that can be modelled with the Bohr model - it is actually just what the Bohr model gives for the energy of each level.

This is because when heated, the atom gains energy. The electron in the atom will be excited to a higher energy level. After a while, it would lose the gained energy and release the gained energy in the form of light. Hence, coloured light is produced when they release energy. Some elements only produced certain colour because of the energy required to excite from one state to another are different from other elements. Elements can only be excited from one state to another with specific energy. In other word, the energy is quantised. This is related to the quantum theory. More info can be found on the net and textbook.

ONE THING IT MUST HAVE POTENTIAL ENERGY BUT FOR YOUR CONVENIENCE I ASSUME IT HAS 0 KE & PE\nTHE TOTAL ENERGY OF A SYSTEM REMAINS CONSTANT SO IT MUST HAVE "ZERO" END ENERGY
