A geologist would ask the analytical chemist to identify the rock's composition. Chemists gather data from afar and analyze matter back to earth.
<h3>Who is a geologist ?</h3>
A geologist is a scientist who focuses on the processes that shape terrestrial planets and the solid, liquid, and gaseous stuff that makes up Earth. Although training in physics, chemistry, biology, and other sciences are sometimes helpful, geologists typically pursue geology as their field of study. Geology includes a significant amount of field study (field work), even if many of its subdisciplines also involve laboratory and computer work.
Geologists look for natural resources like oil, gas, precious and base metals in the energy and mining industries. They are also in the vanguard of efforts to prevent and lessen the effects of natural disasters and hazards like earthquakes, volcanoes, tsunamis, and landslides.

Answer:
1s2 2s2 2p6 3s2 3p6
Explanation:
Calcium is the 20th element. It has 20 electrons in it's neutral state. The electronic configuration is given as;
1s2 2s2 2p6 3s2 3p6 4s2
However in the compound; calcium chloride, it does not exist in it's neutral state.
CaCl2 --> Ca2+ + Cl-
In Ca2+ state, it has lost two electrons, The total number of electrons becomes; 20 - 2 = 18 electrons.
The electronic configuration is given as;
1s2 2s2 2p6 3s2 3p6
