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: o²⁻

Explanation:

Step1: Determine the element from protons

The number of protons is equal to the atomic number. Since there are 8 protons, the element is oxygen (O), as oxygen has an atomic number of 8.

Step2: Determine the charge from protons and electrons

The charge of an ion is calculated as (number of protons - number of electrons). Here, protons = 8 and electrons = 10. So charge = \(8 - 10 = -2\).

Step3: Write the ion symbol

The element is O, and the charge is -2, so the ion symbol is \(O^{2-}\).

Answer:

\(O^{2-}\)
