Question

question 10 identify the parts below for $_8^{16}o^{-2}$

Explanation:

Step1: Identify atomic number

The sub - script 8 is the atomic number. Atomic number = 8.

Step2: Identify mass number

The super - script 16 is the mass number. Mass number = 16.

Step3: Determine number of protons

Protons equal atomic number. Protons = 8.

Step4: Calculate number of neutrons

Neutrons = Mass number - Protons. So, Neutrons = 16 - 8=8.

Step5: Determine number of electrons

The ion has a charge of - 2, meaning it has 2 extra electrons. For a neutral atom of oxygen (atomic number 8), number of electrons = 8. So for \(O^{-2}\), electrons = 8 + 2=10.

Step6: Identify charge

The charge is - 2.

Step7: Identify element name

The element is oxygen.

Step8: Identify type of ion

Since it has a negative charge, it is an anion.

Answer:

Atomic Number: 8
Mass Number: 16
Protons: 8
Neutrons: 8
Electrons: 10
Charge: - 2
Element Name: Oxygen
Type of Ion: Anion
