Question

apply the rules of a = p = e
atomic # =
atomic mass =

of protons =

of neutrons =

of electrons =

Explanation:

Step1: Identify Atomic Number

The atomic number is given at the top of the element box. For oxygen (\(O\)), it is \(8\).

Step2: Identify Atomic Mass

The atomic mass is at the bottom of the element box. For oxygen (\(O\)), it is \(15.999\).

Step3: Determine Protons

In a neutral atom, the number of protons (\(P\)) equals the atomic number (\(A\)). So, protons \(= 8\).

Step4: Determine Neutrons

Neutrons (\(N\)) = Atomic Mass (rounded to whole number, \(16\)) - Protons. \(16 - 8=8\).

Step5: Determine Electrons

In a neutral atom, electrons (\(E\)) = protons. So, electrons \(= 8\).

Answer:

Atomic # = \(8\)
Atomic Mass = \(15.999\)

of Protons = \(8\)

of Neutrons = \(8\)

of Electrons = \(8\)
