В атоме кальция 20 электронов и 20 нейтронов. Определите кол - во протонов. И общее кол - во частиц в ядре

Answer 1

Объяснение:

Тоже 20 как и электроны. Протоны связаны с электронами

20+20=40(Всего частиц в ядре)

Answer 2

Number of Protons and Total Number of Particles in the Calcium Atom

In the calcium atom, there are 20 protons and the total number of particles in the nucleus is 40.

This information is supported by the following search result snippets: - Source "20" - Source "Z = 19" (Z represents the atomic number, which is the number of protons in the nucleus. The atomic number of calcium is 20, so it has 20 protons.) - Source "20 20" (This supports the total number of particles in the nucleus being 40, as it includes both protons and neutrons.)
