where am i found beta ray spectrum for sodium(24)?

I didnt get the question

a beta particle is a high energy electron. origin of this is neutrons in the nuclues. when a negative charge particle emit from the zero charged nuetrron, the result is a positively charged proton. So the atomic number incrase\n\nNeutron (0) - Beta (-1)  =  Proton ( +1)

so you plot the proton number on the y-axis, and the different melting points of the elements across the x- axis.. actually are sure it has to be a bar graph.. i think a line/scatter graph would be more accurate maybe?

http://www.orau.org/ptp/museumdirectory.htm\n\ngo to this link.  it has one of the finest museums on-line dealing with the detection of radiation...and other neat stuff

is you mean mass spectroscopy.. try this link...

Protons and neutrons.

Check out this website it will tell you all you would ever want to know about radon and any other element.\n\nhttp://www.lenntech.com/Periodic-chart-elements/Rn-en.htm

this ones pretty simple:\nhttp://www.nasa.gov/centers/langley/images/content/114284main_EM_Spectrum500.jpg\nor pick one from here:\nhttp://images.google.com.au/images?q=electromagnetic+spectrum&hl=en&btnG=Search+Images

i presume you have the energy values for the different levels?\n\nif so you use the equation E=hc/lamda to find the wavelength for each energy transition in the series.\n\nThe red line will be about 575nm and the purple line will be about 375nm.

atomic mass of S = 32.07, 64 grams of S = 64/32.07 ~= 2 moles\natomic mass of Be = 9.01, 20 grams of Be = 20/9.01 ~= 2.2 moles\natomic mass of Na = 22.99, 25 grams of Na = 25/22.99 ~= 1.1 moles.\n\nThe Na sample has the fewest atoms, followed by K, then S, then Be.

I don't remember the atomic weight of Sodium offhand so I can't give you the exact answer but here's how to figure it out:\n\nDivide 10.4 by the atomic weight of Na (see the periodic table).  That will give you the number of moles of Na in 10.4 g.\n\nMultiply that number by Avogadro's number (6.023 x 10^23) to get the number of atoms.

These could be, for example:\n\nEmission Line Spectrum\nAbsorption Line Spectrum

you don't. to determine the neutrons you have to know the atomic number(identity) and the atomic mass. then subtract.

I'd expect to find it grouped with alkali metals, atomic number 11, Group 1, Period 3, Block s :)

Beta decay is when an electron is fired out from the nucleus. Since the nucleus doesn't inherently contain electrons, an Neutron has to change to a Proton+Electron first so that the electron can be fired out.\n\nthe Atomic number therefore increases by 1.\n\ne.g.\n\nC6 -> N7 + β

None of them.  \nTechnetium has been observed both in spectral star signatures, and in very small quantities in pitchblende.  To quote from Wickepedia "In 1962, technetium-99 was isolated and identified in pitchblende from the Belgian Congo in very small quantities (about 0.2 ng/kg); there it originates as a spontaneous fission product of uranium-238. This discovery was made by B.T. Kenna and P.K. Kuroda."
