Question

write the ion symbol for an atom with the given number of protons and electrons. part 1 of 2 8 protons and 10 electrons:

Explanation:

Step1: Identify the element

The number of protons is 8. The element with atomic number (number of protons) 8 is oxygen (O).

Step2: Determine the charge

The number of electrons is 10, and the number of protons is 8. Charge = number of protons - number of electrons = \(8 - 10 = -2\).

Step3: Write the ion symbol

The ion symbol for oxygen with a charge of -2 is \(O^{2-}\).

Answer:

\(O^{2-}\)
