10. complete the following table by filling each line with the correct value.\nelement atomic number mass number number of protons number of neutrons number of electrons\ncarbon - 12 12 6\nhydrogen - 1 0 1\nphosphorus - 31 31 15\nfluorine - 19 9\ncarbon - 13
Answer
Explanation:
Step1: Recall atomic - number rules
The atomic number is equal to the number of protons. For a neutral atom, the number of electrons is equal to the number of protons. The mass number is the sum of the number of protons and neutrons.
Step2: Fill in Carbon - 12
The atomic number of carbon is 6. Since it is neutral, the number of electrons is 6. The number of neutrons = mass number - number of protons = 12 - 6=6.
| Element | Atomic number | Mass number | Number of protons | Number of neutrons | Number of electrons |
|---|---|---|---|---|---|
| Carbon - 12 | 6 | 12 | 6 | 6 | 6 |
Step3: Fill in Hydrogen - 1
The atomic number of hydrogen is 1. Since it is neutral, the number of electrons is 1. The number of neutrons = mass number - number of protons = 1 - 1 = 0.
| Element | Atomic number | Mass number | Number of protons | Number of neutrons | Number of electrons |
|---|---|---|---|---|---|
| Hydrogen - 1 | 1 | 1 | 1 | 0 | 1 |
Step4: Fill in Phosphorus - 31
The atomic number of phosphorus is 15. Since it is neutral, the number of electrons is 15. The number of neutrons = mass number - number of protons = 31 - 15 = 16.
| Element | Atomic number | Mass number | Number of protons | Number of neutrons | Number of electrons |
|---|---|---|---|---|---|
| Phosphorus - 31 | 15 | 31 | 15 | 16 | 15 |
Step5: Fill in Fluorine - 19
The atomic number of fluorine is 9. Since it is neutral, the number of electrons is 9. The number of neutrons = mass number - number of protons = 19 - 9 = 10.
| Element | Atomic number | Mass number | Number of protons | Number of neutrons | Number of electrons |
|---|---|---|---|---|---|
| Fluorine - 19 | 9 | 19 | 9 | 10 | 9 |
Step6: Fill in Carbon - 13
The atomic number of carbon is 6. Since it is neutral, the number of electrons is 6. The number of neutrons = mass number - number of protons = 13 - 6 = 7.
| Element | Atomic number | Mass number | Number of protons | Number of neutrons | Number of electrons |
|---|---|---|---|---|---|
| Carbon - 13 | 6 | 13 | 6 | 7 | 6 |
Answer:
| Element | Atomic number | Mass number | Number of protons | Number of neutrons | Number of electrons |
|---|---|---|---|---|---|
| Carbon - 12 | 6 | 12 | 6 | 6 | 6 |
| Hydrogen - 1 | 1 | 1 | 1 | 0 | 1 |
| Phosphorus - 31 | 15 | 31 | 15 | 16 | 15 |
| Fluorine - 19 | 9 | 19 | 9 | 10 | 9 |
| Carbon - 13 | 6 | 13 | 6 | 7 | 6 |
