Protactinium 234 is a decay product of thorium 234; the nuclear reaction is:
23490Th---------------23491Pa + beta rays (e-)
You'd have to specify the isotope of thorium for us to definitively identify the isotope produced. A thorium atom that undergoes alpha decay will become a radium atom. However, we can't identify the specific isotope of radium without knowing the number of neutrons in the original thorium atom.
Alpha decay occurs when thorium-231 undergoes radioactive decay to form protactinium-231. In alpha decay, a nucleus emits an alpha particle (two protons and two neutrons) to transform into a nucleus with a lower atomic number.
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 :)
1 degree Celsius plus 1 degree Celsius equals 2 degrees Celsius. Temperature reading is a linear scale, so you can add and subtract values directly in Celsius.
It is not yet discovered since all of the uranium isotopes are having half life for several millions of years. We would be able to find it after atleast 700 millions of years.
After 96 days, there would be approximately 1 gram of Thorium-234 left from the initial 4 grams. Thorium-234 has a half-life of 24.1 days, so after each half-life, the amount of Thorium-234 would be halved.
234 is the mass of that particular Uranium isotope. Exactly 234,040 952 088 ± 0,000 001 960 u.a.
In the uranium series, 4n + 2 represents the decay process of uranium-238 (238U) where it undergoes alpha decay to form thorium-234 (234Th) by emitting an alpha particle. The equation indicates that for every 1 decay of uranium-238, 1 thorium-234 and 2 alpha particles are produced.
You'd have to specify the isotope of thorium for us to definitively identify the isotope produced. A thorium atom that undergoes alpha decay will become a radium atom. However, we can't identify the specific isotope of radium without knowing the number of neutrons in the original thorium atom.

The reason lies with the way in which the operation "plus" is defined and the way in which numbers are represented.

It's beta decay. Actually, it's beta minus decay. A neutron in the nucleus of thorium-234 undergoes beta minus decay and changes into a proton with the subsequent release of an electron, an antineutrino and some energy. The transformation of a neutron in the thorium nucleus into that proton creates another element. You'll recall that the identity of an element is determined solely by the number of protons in its nucleus. And our thorium atom has now become a protractinium-234 atom.

234 = 234/1 is a fraction which is greater than 1.

The melting point of thorium is 1 750 0C.The boiling point of thorium is 4 788 0C.
If it's country code +234 (Nigeria), dial the international access prefix (011 from the US), country code 234, and the Nigerian number (omitting the leading zero). If it's area code +1 234 (Akron/Canton/Youngstown, OH), dial "one-plus"
