Question

Рассчитать число протонов, нейтронов и электронов в атомах: Cl, O, Mg, P.

Answer 1

Вот держи...............,

Answer 2

Cl : число протонов= числу электронов = 17, нейтронов = 35-17 =18
O : число протонов = число электронов = 8, нейтронов = 16-8=8
Mg : число протонов = числу электронов = 12, нейтронов = 24-12=12
P : число протонов=числу электронов = 15, нейтронов = 31-15=16

Calculation of Protons, Neutrons, and Electrons in Atoms

To calculate the number of protons, neutrons, and electrons in atoms, we need to refer to the atomic number and atomic mass of each element. Here are the calculations for the atoms you mentioned:

1. Chlorine (Cl): - Atomic number (Z): 17 - Atomic mass (A): 35.5 - Number of protons (Z): 17 - Number of neutrons (A - Z): 35.5 - 17 = 18.5 (rounded to 19) - Number of electrons (Z): 17

2. Oxygen (O): - Atomic number (Z): 8 - Atomic mass (A): 16 - Number of protons (Z): 8 - Number of neutrons (A - Z): 16 - 8 = 8 - Number of electrons (Z): 8

3. Magnesium (Mg): - Atomic number (Z): 12 - Atomic mass (A): 24.305 - Number of protons (Z): 12 - Number of neutrons (A - Z): 24.305 - 12 = 12.305 (rounded to 12) - Number of electrons (Z): 12

4. Phosphorus (P): - Atomic number (Z): 15 - Atomic mass (A): 31 - Number of protons (Z): 15 - Number of neutrons (A - Z): 31 - 15 = 16 - Number of electrons (Z): 15

Please note that the atomic mass values provided are approximate and rounded. The actual values may vary slightly.
