How Many Electrons Are There In The Following Ion? Enter A Number.$^{15}O^{2-}$
The ion is a negatively charged oxygen atom with a mass number of 15 and a charge of -2. To determine the number of electrons in this ion, we need to understand the structure of the atom and how it gains or loses electrons to form ions.
Atomic Structure and Electron Configuration
An atom consists of protons, neutrons, and electrons. Protons and neutrons are found in the nucleus, while electrons orbit around the nucleus in energy levels or shells. The number of protons in an atom determines the element, while the number of neutrons determines the isotope.
In the case of oxygen, the atomic number is 8, which means it has 8 protons and 8 electrons in its neutral state. The mass number of 15 indicates that the oxygen atom has 7 neutrons.
Forming the Ion:
To form the ion , the oxygen atom gains 2 electrons. This is because the charge of the ion is -2, which means it has 2 more electrons than the neutral atom.
Determining the Number of Electrons in the Ion
To determine the number of electrons in the ion , we need to add the number of electrons in the neutral atom to the number of electrons gained to form the ion.
The number of electrons in the neutral oxygen atom is 8. To form the ion , the oxygen atom gains 2 electrons. Therefore, the total number of electrons in the ion is:
8 (electrons in the neutral atom) + 2 (electrons gained) = 10
Conclusion
In conclusion, the number of electrons in the ion is 10. This is determined by adding the number of electrons in the neutral oxygen atom to the number of electrons gained to form the ion.
Key Takeaways
- The number of electrons in an atom determines its charge.
- To form an ion, an atom gains or loses electrons.
- The number of electrons in an ion can be determined by adding the number of electrons in the neutral atom to the number of electrons gained or lost.
