question how many electrons are in the ion? refer to this periodic table to help answer the question. type the correct answer in the box. an ion of the element oxygen (o) has an overall charge of 2-. therefore, the number of electrons in this oxygen ion is
Answer
Explanation:
Step1: Find oxygen's atomic number
Oxygen's atomic number is 8, which means a neutral oxygen atom has 8 electrons.
Step2: Consider the ion's charge
The oxygen ion has a charge of 2-. This means it has gained 2 electrons.
Step3: Calculate number of electrons
The number of electrons in the oxygen - 2 ion is 8 + 2. $8+2 = 10$
Answer:
10
