CHEMISTRY OMG

ask Meez or quad

X:) hi Cybergamesboy

first!

edit:fu crypt0

Ask from Chernobyl.

Wtf in what year are you ? We havent saw that (or atleast not in English lol)yet

Ah no wonder , I'm at 2nd year of 2nd grade ^^ , you are 1-2 years ahead of me :P

erm... i'm not that good in chemistry... try http://en.wikipedia.org/wiki/Radiation

studying clinical chemistry SORRY

1. beta radation -> electron
2. alpha radation -> helium particle

alpha radiation: positive particles
beta radiation: negative particles
gamma radiation: particles with a Coulomb(dont know the word 'lading' in english omg :D)

gamma radiation are X-ray what means they can only be 'moved' by magnetic fiels or other electric particles or whatever :D

my english suck :(

I guess that works as to why the nucleon number and the atomic number changes, but I was just unsure on how alpha radiation really works

learned that on 8 grade lolz

The radioactive process described in the first question is a beta decay. It could either be a beta-minus decay or a beta-plus decay. In a beta-minus decay, an electron is emitted along with an anti-neutrino. This happens because a neutron in the nucleus transforms into a proton, an electron and an anti-neutrino. Meanwhile, in a beta-plus decay, a positron is emitted along with a neutrino because a proton in the nucleus transforms into a neutron, a positron and a neutrino. You see, in both cases, the atomic number changes while the nucleon number remains the same. So, if you want to know what particles result from this kind of decay, the answer is an electron/positron along with an anti-neutrino/neutrino respectively.

The radioactive process described in the second question is no doubt an alpha decay. In an alpha decay, the nucleus is transformed into a different nuclide by emitting an alpha particle (a helium nucleus). Since a helium nucleus contains two protons and two neutrons, both the atomic number and the nucleon number of the parent nucleus must change when it emits such a particle. If you want to know what particle results from this kind of decay, the answer is an alpha particle (a helium nucleus).

I don't know if you have translated the questions correctly, however, as it seems a bit odd to call these "resulting" particles radioactive. Also, this is definitely physics!

Too easy :p

dont pretend that you actually study chemistry in Malta :DD

Ive seen you people in your uniforms, school finishes at 12:30 like everyday!!

1. beta, electron gets emitted
2. alpha, because everyone else says so :D

Fuck chemistry. Physics > Chemistry!
