Question

Рассчитайте число протонов электронов и нейтронов для атомов Si, Zn

Answer 1

Si 14 протонов, 14 нейтронов и 14 электронов, Zn 30 прттонов 30 электронов и 35 нейтронов

Answer 2

Si - кремний.порядковый номер=заряд атома=p
n=A-p 
p=14; n=14; e=14; A=28
.
Zn-цинк, порядковый номер 30.
p=30; e=30; A=35; n=65-30=35

Answer 3

Calculating the Number of Protons, Electrons, and Neutrons for Si and Zn Atoms

To calculate the number of protons, electrons, and neutrons for the atoms Si and Zn, we can use the atomic number (Z) and the atomic mass number (A) for each element.

Silicon (Si): - Atomic number (Z) for silicon is 14. - Atomic mass number (A) for silicon is approximately 28.0855 u.

Using the atomic number and atomic mass number, we can calculate the number of protons, electrons, and neutrons for silicon.

Zinc (Zn): - Atomic number (Z) for zinc is 30. - Atomic mass number (A) for zinc is approximately 65.38 u.

Similarly, using the atomic number and atomic mass number, we can calculate the number of protons, electrons, and neutrons for zinc.

Let's calculate the number of protons, electrons, and neutrons for silicon and zinc based on the provided information.

Calculations:

Silicon (Si): - Number of protons (Z): 14 - Number of electrons: 14 (in a neutral atom) - Number of neutrons (A - Z): Approximately 14

Zinc (Zn): - Number of protons (Z): 30 - Number of electrons: 30 (in a neutral atom) - Number of neutrons (A - Z): Approximately 35

Based on the provided atomic numbers and atomic mass numbers, the calculations for the number of protons, electrons, and neutrons for silicon and zinc atoms are as follows:

Silicon (Si): - Number of protons: 14 - Number of electrons: 14 - Number of neutrons: Approximately 14

Zinc (Zn): - Number of protons: 30 - Number of electrons: 30 - Number of neutrons: Approximately 35

These calculations are based on the atomic numbers and atomic mass numbers provided for silicon and zinc.
