A particle that contains 8 protons, 9 neutrons and 7 electrons could be written as
- A)\(^{16}_8O\)
- B)\(^{17}_8O^+\)
- C)\(^{17}_9O^+\)
- D)\(^{17}_8O\)
Correct Answer: B)\(^{17}_8O^+\)
Explanation
The correct answer is Option B: \(^{17}_8O^+\).
The atomic number (the subscript in the notation) is the number of protons in an atom, which is 8 in this case. This identifies the atom as oxygen (O).
The mass number (the superscript in the notation) is the sum of the number of protons and neutrons in an atom. In this case, 8 protons + 9 neutrons = 17.
The charge of the atom is determined by the difference between the number of protons and electrons. In this case, 8 protons - 7 electrons = +1. This is represented by the superscript + after the symbol.
So, the notation for a particle with 8 protons, 9 neutrons, and 7 electrons is \(^{17}_8O^+\).
