Question

give the ion symbol for the ion that has 27 protons and 24 electrons.

Explanation:

Step1: Determine the element

The number of protons is equal to the atomic number. An element with atomic number \(27\) is cobalt (\(Co\)).

Step2: Calculate the charge

The charge of an ion is given by \(q = \text{number of protons}-\text{number of electrons}\).
Substituting the values: \(q=27 - 24=3\).

Answer:

\(Co^{3 +}\)
