Question

Число протонов,нейтронов и электронов в атоме фосфора равно соответственно:

Answer 1

Число протонов - 15
Число электронов - 15
Число нейтронов - 16
Прошу вас. 
Число электронов и протонов равно порядковому номеру. А число нейтронов вычисляется по формуле: N = A - Z, где A - относительная атомная масса, а Z - порядковый номер.

Answer 2

Atom of Phosphorus: Number of Protons, Neutrons, and Electrons

The number of protons, neutrons, and electrons in an atom of phosphorus is as follows:

- Protons: 15 - Neutrons: 16 - Electrons: 15

These numbers are based on the atomic number and atomic mass of phosphorus.

The atomic number of phosphorus is the number of protons in its nucleus, which is 15. The atomic mass of phosphorus is the sum of its protons and neutrons, which is approximately 31. Therefore, the number of neutrons in phosphorus is calculated as 31 (atomic mass) - 15 (protons) = 16 neutrons.

The number of electrons in a neutral atom is equal to the number of protons, which is 15.

Therefore, the number of protons, neutrons, and electrons in an atom of phosphorus is 15, 16, and 15 respectively.
