Question

СРОЧНО!!ЕСЛИ ЯДРО СОСТОИТ ИЗ 92 ПРОТООВ И 144 НЕЙТРОНОВ,ТО ПОСЛЕ ИСПУСКАНИЯ ДВУХ АЛЬФА ЧАСТИЦ И ОДНОЙ БЕТА, ОБРАЗОВАВШИЕСЯ ЯДРО БУДЕТ СОСТОЯТЬ ИЗ ПРОТОНОВ И НЕЙТРОНОВ!!

Answer 1

92 протонов и 144 нейтрона это U - 2 альфа частицы - одна бета = 84 протона и (не уверена) 139 нейтронов это Po

Answer 2

Nuclear Composition and Decay

The composition of an atomic nucleus is determined by the number of protons and neutrons it contains. Protons have a positive charge, while neutrons have no charge. The total number of protons in an atom is called the atomic number, and it determines the element to which the atom belongs. Neutrons, on the other hand, contribute to the stability of the nucleus.

Based on the information provided, if a nucleus consists of 92 protons and 144 neutrons, and two alpha particles (each consisting of 2 protons and 2 neutrons) and one beta particle (consisting of an electron) are emitted, the resulting nucleus will still consist of protons and neutrons.

To determine the composition of the resulting nucleus, we need to subtract the number of protons and neutrons emitted from the original nucleus.

Let's calculate the resulting number of protons and neutrons in the nucleus after the emission of two alpha particles and one beta particle:

Original nucleus: - Protons: 92 - Neutrons: 144

Alpha particles: - Protons: 2 * 2 = 4 - Neutrons: 2 * 2 = 4

Beta particle: - No change in the number of protons and neutrons.

Calculating the resulting nucleus: - Protons: 92 - 4 = 88 - Neutrons: 144 - 4 = 140

Therefore, the resulting nucleus will consist of 88 protons and 140 neutrons.

Please note that the information provided is based on the assumption that the emission of the particles does not cause any further changes in the nucleus. The actual decay process can be more complex and may involve additional particles or reactions.
