Question

question 8 gold has protons neutrons electrons

Explanation:

Step1: Recall atomic number property

The atomic number is equal to the number of protons. For gold (Au), the atomic number is 79, so the number of protons is 79.

Step2: Recall electron - proton relationship

In a neutral atom, the number of electrons is equal to the number of protons. So the number of electrons in gold is 79.

Step3: Calculate number of neutrons

The mass number is approximately 197 (from 196.967). The number of neutrons = mass number - number of protons. So, number of neutrons = 197 - 79 = 118.

Answer:

Protons: 79
Neutrons: 118
Electrons: 79
