atomic number:\natomic mass (rounded):\nnumber of protons:\nnumber of neutrons:\nnumber of electrons:
Answer
Explanation:
Step1: Recall atomic number facts
The atomic number is equal to the number of protons and the number of electrons in a neutral atom. The atomic mass (rounded) is approximately the sum of protons and neutrons.
Step2: For Oxygen (O)
Atomic number = 8. So number of protons = 8, number of electrons = 8. Atomic mass rounded to 16. Number of neutrons = 16 - 8=8.
Step3: For Zinc (Zn)
Atomic number = 30. So number of protons = 30, number of electrons = 30. Atomic mass rounded to 65. Number of neutrons = 65 - 30 = 35.
Step4: For Silicon (Si)
Atomic number = 14. So number of protons = 14, number of electrons = 14. Atomic mass rounded to 28. Number of neutrons = 28 - 14 = 14.
| Element | Atomic Mass (rounded) | Number of Protons | Number of Neutrons | Number of Electrons |
|---|---|---|---|---|
| Oxygen (O) | 16 | 8 | 8 | 8 |
| Zinc (Zn) | 65 | 30 | 35 | 30 |
| Silicon (Si) | 28 | 14 | 14 | 14 |
Answer:
| Element | Atomic Mass (rounded) | Number of Protons | Number of Neutrons | Number of Electrons |
|---|---|---|---|---|
| Oxygen (O) | 16 | 8 | 8 | 8 |
| Zinc (Zn) | 65 | 30 | 35 | 30 |
| Silicon (Si) | 28 | 14 | 14 | 14 |
