D. all of these
Explanation:
All of given choices are the physical properties of the gold as given by the table.
Color is also a physical property.
Ionization potential and electronegativity are chemical properties of the metal.
The physical property of a substance tells us everything about a substance when no change is occurring to it.
Such properties are observed with our sense or instruments or pieces of apparatus.
- Examples are color of matter, state of matter, odor, taste, density, boiling point, melting point, solubility, hardness, texture etc

Answer: You need to include for info because we cant help with this unless we have more information on how I would love to help you
Explanation:
The answer is fjdjsbsjeiegeididbdbeiejdbdj A
Calcium ions have a charge of “2+”because they are in group two (column number 2)
Skip over the transition metals
Fluoride ions would have a charge of
“1-” because they are all the way near the end of the table in the second last group (group 7)
Hope that helps :)
