What do the lines between atoms mean?
A dashed line represents a hydrogen bond because they are the weakest of the bonds.
How does fusion differ for high mass stars and low mass stars?
Nuclear Fusion in a Giant Star involves Helium being fused into a hydrogen shell that surrounds the core, and Nuclear Fusion in a Main-Sequence star involves Hydrogen being fused into Helium to produce Energy inside of the core.
Which nonmetal is not located to the right of the zig zag line?
hydrogen
Who created the hydrogen line emission spectrum?
Niels Bohr in 1913.
Who used planck's idea of quantization to explain the line spectrum of hydrogen?
Bohr
What do the lines between atoms mean?
A dashed line represents a hydrogen bond because they are the weakest of the bonds.
Why are the hydrogen Balmer lines strong in the spectra of medium-temperature stars and weak in the spectra of hot and cool stars?
They are like this due to the fact that most hydrogen atoms are ionized which makes a weaker balmer line. The strength of the Balmer line is sensitive to temperature so that's why it occurs more in the middle. The hot end of the hydrogen is low Balmer line due to them being in the ground state. Hope that's answers it =] -CRS
What is The difference between an original and derivative classified document?
Original classified document will have a classified by and a reason line and a derivative classified document will have a classified by and a derived from line
The difference between an original and derivative classified document is?
Original classified document will have a classified by and reason line and a derivative classified document will have a classified by and derived from line
Is hydrogen can be over?
Although all the hydrogen in the sun and the stars will eventually be converted to helium or heavier elements, there is likely to be plenty of hydrogen atoms in outer space. This answer assumes, in line with current cosmological theories, that the universe does not end in a big crunch.
What supernova type is older type 1 or 2?
Supernova [See Link] classifications are based on chemical composition, not time.They are classified according to the absorption lines of different chemical elements that appear in their spectra.The first element for a division is the presence or absence of a line caused by hydrogen. If a supernova's spectrum contains a line of hydrogen in the visual portion of the spectrum) it is classified Type II; otherwise it is Type I.
Which line in the classification authority block will always appear on originally classified information but not on derivatively classified information?
The subject line of a classified email is used as a banner line that marks the overall classification of the email
What does it mean when stars are in line?
When the stars are in line is means everything will come together in a positive way. It is believed good things happen to you when the stars are in line.
Why is the H alpha absorption line of hydrogen in the sun relatively weak even though the Sun has abundant hydrogen?
Good question. It's because of the Sun's temperature. H-alpha is the line produced from exciting an electron from n=2 to n=3 level. Note that to be able to absorb H-alpha, you would need to have a hydrogen atom with its electron already in the n=2 excited state! Exciting n=1 to n=2 (Lyman-alpha) takes a lot of energy, much more than n=2 to n=3, and the Sun's photosphere is not hot enough for much of its hydrogen to be in the n=2 excited state. Hotter stars have more hydrogen in the n=2 state, so it is then easy to do the (less energetic) n=2 to n=3 H-alpha absorption. That's why hotter stars like A stars have much stronger H-alpha lines. Note that stars hotter than A stars (O,B) again have weak hydrogen absorption lines, because they are so hot most of their hydrogen is ionized, and again there is not much hydrgoen in the n=2 state to excite.
When do stars become stars?
The dividing line is usually considered to be when the accretion process stops and the T tauri wind begins. This is probably approximately coincident with the beginning of lithium fusion (a T tauri star is not yet hot and dense enough for hydrogen fusion to start).
What do stars in a row mean?
In a row means one after another on the same line. So "stars in a row" mean there are stars one after another all on the same line.
Is the milky way in line with a path of stars?
The Milky Way is a huge group of stars, somewhere between 200 and 400 billion stars. The stars themselves, or the Milky Way in its entirety, is not in line with anything.
