When an electron goes from a higher state to a lower state, it gives up energy equal to the difference of energy levels of the two states. This energy is in the form of a photon. If it goes directly from n=3 to n=1, then 1 photon is emitted. If it transitions from n=3 to n=2, then from n=2 to n=1, two (2) photons are emitted.
Energy level of n=3 for Hydrogen is -1.511 eV (electron volts)
Energy level of n=2 for Hydrogen is -3.4 eV (electron volts)
Energy level of n=3 for Hydrogen is -13.6 eV (electron volts)
The energy levels are 'more negative' at lower levels because the electron becomes more bound to the atom.
From n=3 to 1 (gives up 12.089 eV, or a photon with wavelength 102.518 nm - ultraviolet light)
From n=3 to 2 (gives up 1.889 eV, or a photon with wavelength 656.112 nm - red light)
From n=2 to 1 (gives up 10.2 eV, or a photon with wavelength 121.5 nm - ultraviolet)

Nothing. Once you enter into a put contract, the strike price remains the same. If the stock price goes over the strike price and stays there until expiration, you just let the put expire.

the x axes is the bold line that goes horizontally the one that goes vertically is the y axes!
To simplify, you could put the equation into slope-intercept form (y=mx+b) giving you y=3/2x+1/2. From there you put in values of x and the equation gives you y-values. take each coordinate pair and place it on the graph: X Y 1 2 2 3.5 3 5 4 6.5 5 8 from there, the slope would be 3/2, as in it goes up 3 units every time it goes over 2 units, and it intersects the y-axis at 1/2.
The multiples of 20 are: 20,40,60,80,100,120,140,160,180,200,220.... The list goes on and on.
In the reaction of hydrogen with iodine, hydrogen is oxidized. This is because hydrogen goes from an oxidation state of 0 to +1, indicating loss of electrons, while iodine is reduced from an oxidation state of 0 to -1, indicating gain of electrons.
Oxygen is reduced in the reaction of hydrogen with oxygen to make water because it gains electrons from hydrogen to form water molecules. Reduction involves the gain of electrons, and in this reaction, oxygen goes from an oxidation state of 0 in O2 to -2 in H2O, indicating reduction.
The electrons in the oxygen and hydrogen have a high amount of energy which is released when the oxygen and hydrogen combine to form water. The electrons are in a more stable set of bonds. The water then has no chance of bonding to decrease energy, so the water absorbs heat by cooling and boiling, so that the fire goes out.
Oxidation is the loss of electrons. Reduction is the gain of electrons. The oxidizing agent is reduced. The reducing agent is oxidized. Cu goes from 0 to +2, it lost electrons S went from +6 to +4, it gained electrons I went from 0 to +5, it lost electrons N went from +5 to +4, it gained electrons.
In the reaction of hydrogen with oxygen to make water, oxygen is reduced because it gains electrons from hydrogen. Reduction is the gain of electrons, and in this reaction, oxygen is reduced from an oxidation state of 0 in O2 to an oxidation state of -2 in H2O by accepting electrons from hydrogen atoms.
Farmers because most of the hydrogen that is produced goes into fertiliser
Lithium is element #3, and it has 3 electrons.
This is a trick question, since hydrogen does not form ionic bonds, only covalent bonds (or in some cases, what are called hydrogen bonds). But if you were to ask if hydrogen tends more toward being a donor of electrons (i.e., a metal) or a recipient of electrons (i.e., a non-metal) hydrogen tends to donate electrons. For example in water, H2O, all three atoms share the valence electrons (which is what makes this a covalent bond) however the electrons spend more time in the vicinity of the oxygen atom then they do in the vicinity of the two hydrogen atoms.I am going to make an addition to this answer. The element hydrogen, which is immensely important in organic chemistry, is almost always found as I described it, forming covalent bonds and having a metallic role, tending to donate electrons. However, there are other possible hydrogen compounds, such as lithium hydride (LiH) in which hydrogen does form an ionic bond, and in which it acts as an electron recipient rather than an electron donor. Hydrogen has an electronegativity that is intermediary between metal and non-metal, so it can take on either role. However, it is very rare to encounter lithium hydride, in comparison to compounds such as water, methane, ammonia, etc., in which hydrogen has the characteristics of a metal.

it goes to the other formed water molecule, there are 2 oxygen atoms in 2 molecules of water
