give the ion symbol for the ion that has 15 protons and 18 electrons.
give the ion symbol for the ion that has 15 protons and 18 electrons.
Answer
Explanation:
Step1: Determine the element
The number of protons determines the element. With 15 protons, the element is phosphorus (P).
Step2: Calculate the charge
The charge of an ion is calculated as ( \text{Charge} = \text{Number of protons}-\text{Number of electrons} ). Substituting the values: ( \text{Charge}=15 - 18=- 3)
Answer:
(P^{3 -})
