Question

Запишіть рівняння реакції для елементу 234 91 Рa, якщо відомо, що з ядра випускається β-частинка. На ядро якого елементу перетворюється при цьому ядро атома Протактинію?

Answer 1

Ответ:

ядро атома протактиний превращается в ядро урана.

Answer 2

Writing the Equation for the Reaction

The equation for the reaction involving the element 234/91 Pa emitting a β- particle and transforming into another element can be represented as follows:

234/91 Pa → X + β-

Where X represents the resulting element after the emission of the β- particle.

Identifying the Resulting Element

To determine the resulting element when the nucleus of Protactinium-234 emits a β- particle, we need to consider the process of beta decay. During beta decay, a neutron within the nucleus is transformed into a proton, and an electron (β-) and an antineutrino are emitted. This results in the atomic number of the element increasing by one while the mass number remains the same.

Therefore, the resulting element can be identified as follows:

234/91 Pa → 234/92 U + β-

The resulting element after the emission of the β- particle from the nucleus of Protactinium-234 is Uranium-234.

I hope this helps! If you have any further questions, feel free to ask.
