Question

Тышу 8. Розмістити елементи за збільшенням кількості нейтронів атомi: P. N, Mg, C.​

Answer 1

Ответ:

Объяснение:

Щоб визначити число нейтронів елемента потрібно:

від атомної маси елемента відняти його порядковий номер.

Таким чином в нас виходить:

C      12(атомна маса елемента) - 6 (порядковий номер елемента) = 6 нейтронів

N     14-7 = 7 нейтронів

Mg   24-12 = 12 нейтронів

P      31-15 = 16 нейтронів

Answer 2

Ordering Elements by Increasing Number of Neutrons

To order the elements P (Phosphorus), N (Nitrogen), Mg (Magnesium), and C (Carbon) by increasing number of neutrons, we need to look at their atomic structures and determine the number of neutrons in each atom.

1. Phosphorus (P): - Atomic number: 15 - Neutrons: Phosphorus has an atomic mass of approximately 31. Therefore, the number of neutrons can be calculated by subtracting the atomic number from the atomic mass. - Number of neutrons in Phosphorus: 31 - 15 = 16

2. Nitrogen (N): - Atomic number: 7 - Neutrons: Nitrogen has an atomic mass of approximately 14. Therefore, the number of neutrons can be calculated by subtracting the atomic number from the atomic mass. - Number of neutrons in Nitrogen: 14 - 7 = 7

3. Magnesium (Mg): - Atomic number: 12 - Neutrons: Magnesium has an atomic mass of approximately 24. Therefore, the number of neutrons can be calculated by subtracting the atomic number from the atomic mass. - Number of neutrons in Magnesium: 24 - 12 = 12

4. Carbon (C): - Atomic number: 6 - Neutrons: Carbon has an atomic mass of approximately 12. Therefore, the number of neutrons can be calculated by subtracting the atomic number from the atomic mass. - Number of neutrons in Carbon: 12 - 6 = 6

Therefore, the elements arranged in increasing order of the number of neutrons are as follows:

1. Carbon (C) with 6 neutrons. 2. Nitrogen (N) with 7 neutrons. 3. Magnesium (Mg) with 12 neutrons. 4. Phosphorus (P) with 16 neutrons.
