Question

Почему у заряда ядра положительный заряд?

Answer 1

Потому, что ядро состоит из протонов и нейтронов. Нейтроны не имеют заряда, а протоны положительно заряжены. Поэтому заряд ядра положителен. 

Answer 2

Why Does the Nucleus Have a Positive Charge?

The positive charge of the nucleus is due to the presence of protons. Protons are positively charged subatomic particles found within the nucleus of an atom. The number of protons in the nucleus determines the atomic number of the element and gives the atom its unique identity.

The positively charged protons are balanced by the negatively charged electrons orbiting the nucleus, maintaining the overall electrical neutrality of the atom.

The discovery of the proton and its role in the atomic nucleus was a significant development in the field of atomic physics. It provided a deeper understanding of the structure of the atom and laid the foundation for further advancements in the field.

In summary, the positive charge of the nucleus is attributed to the presence of protons, which are positively charged subatomic particles.
