Consider the gold isotope 197au. how many electrons, protons, and neutrons are in a neutral 197au atom?

The 197Au isotope has 79 protons, 79 electrons and 118 neutrons

Explanation:

Step 1: The isotope = 197Au

Step 2: Calculate neutrons, electrons and protons

197 = Number of protons + number of neutrons

Isotopes always have the same proton number ( is the same as the atomic number). For Gold (Au) is this 79.

The number of electrons is equal to the number of protons in a neutral atom. Since we have 79 protons, there are also 79 electrons.

All isotopes of Au have a different number of neutrons.

The number of neutrons = 197 -79 = 118 neutrons

The 197Au isotope has 79 protons, 79 electrons and 118 neutrons

d) a person who learns about the world by observing it.

explanation:

scientist are people who discover why and how things are done and made in the world.
