Answer:
The whole world is covered with rocks.
An element’s properties can be predicted from _____.
the number of its neutrons
its atomic mass
its location in the periodic table
the number of its electrons
A periodic table can be used to forecast an element's properties. As we drop into a group or go across a period in the Periodic Table, we can observe a variety of patterns in the physical and chemical characteristics of the elements. The correct option is C.
Each element's location in the table provides crucial details regarding its composition, characteristics, and behavior during chemical reactions. In particular, you may determine an element's electron configuration that is, how the electrons are arranged around the nucleus by looking at where it is in the periodic table.
The group (vertical column) number in the Periodic Table can be used to calculate an element's number of valence electrons. The chemical characteristics of elements with the same number of valence electrons are comparable.
Thus the correct option is C.

Sahil watched a demonstration in which a scientist combined two substances in a sealed container and analyzed the results. The ending substances did not look the same as the starting substances.Sahil was given a diagram with the repeating groups of atoms that make up the starting substances, plus information about the properties of the starting and ending substances. He created a model of the repeating groups of atoms that might make up the two ending substances.Does his model correctly show why the properties of the ending substances are different from the properties of the starting substances? Describe what could be correct or incorrect about his model.
This model correctly show the chemical reaction that take place in this model.
Is this model show correctly the process?This model correctly show the properties of the ending substances that are different from the properties of the starting substances because the properties of product are different from the reactants.
So we can conclude that this model correctly show the chemical reaction that take place in this model.
