What else can I help you with?
Why was existence of a tiny massive and positively charged nucleus was deduced from the observations?
Why or how? The number of alpha particles deflected was small ... indicating the nucleus was small. The deflection of an even smaller amount of alpha particles almost straight back toward the emitting source proved that the nucleus was heavier than the alpha particle. According to previous atomic theory, the alpha particles should have all gone straight through the metal foil, with none deflected. Math calculations based on the deflection pattern showed that the nucleus was repelling the alpha particles, that they were not actually hitting and bouncing off the nucleus... this showed that the nucleus was positively charged.
Has alpha telecom gone bust?
I have tried make a phone call using alpha telecom unable to do so have the company gone bust
Where do the 2 outer electrons go when Uranium loses an alpha particle?
Electrons do not go anywhere. Alpha decay involves the loss of two protons and two neutrons from the nucleus (it is beta decay which involves the loss of an electron, and other particle changes).
What is a balanced equation for the alpha decay of thorium -232?
Alright so you begin with what you need, this isotope of Protactinium has 234 nucleons, its atomic number is 91, in Beta decay we release an electron, which has no nucleons (protons and neutrons) and an atomic number of -1 so when we take out -1 from 91, so 91 - -1 we get 92, which is of course Uranium, this particular isotope has 234 nucleons, now, to show where it has gone, write the electron in, and add a antineutrino aswell, heres how mine looks. Pa23491 ---> U23491 + e0-1 + antineutrino (a v with a little line above it) Hope this helps :)
How have dental caries improved since the presence of fluorine?
decay has gone down as a result
What is the same as the number of protons in its nucleus?
The number of protons in an atomic nucleus can change by several different mechanisms. Let's look at each one and see what happens.In an atom with "too many" protons in its nucleus, that unstable atom can undergo what is called beta decay. There are two types of beta decay, and the one that could happen here goes by the name beta plus decay. In beta plus decay, a proton in the nucleus of that unstable atom transforms into a neutron. A positron and an antineutrino will be ejected from the nucleus, and the number of protons will have gone down by one. If you guessed that nuclear transmutation has just occurred where one element has transformed into another one, you'd be correct.In some other unstable atoms with "too many" protons in the nucleus, that nucleus could under an electron capture event. In electron capture, the nucleus "pulls in" a nearby electron from one of the inner shells of the atom, and that electron "combines" with a proton to become a neutron. Again, the number of protons in the nucleus goes down by one, and nuclear transmutation has occurred.Lastly, it is possible to bombard atomic nuclei with particles and "knock" protons out of a nucleus that is "hit" by the bombarding particles. There are a few different activities that are carried out in nuclear physics labs to do this, but we'll leave it here for now. Just keep in mind that beta plus decay and electron capture are the two primary methods that unstable nuclei undergo when they change the number of protons they have.

What is other words for not living?
dead, decay, non-living, not breathing, gone, no longer here with us, ect...
What is a differentiated nucleus?
A differentiated nucleus refers to the nucleus of a specialized cell that has undergone structural and functional changes to support its specific role in the body. These changes can include modifications in the organization of chromatin, gene expression patterns, and the presence of unique organelles within the nucleus.

Do you have to download Minecraft to play Minecraft alpha 1.2.6?
You can't play minecraft alpha 1.2.6. You can currently play minecraft beta 1.8 if you buy the game for $21.95 and then play it in the browser or download it to your computer and play it in an application. Alpha 1.2.6 is long gone, and it is not able to be found anywhere, as far as I know.
