Zinc is a bluish-white, lustrous metal. It is brittle at ordinary temperatures but maleable at 100 to 150C. It is a fair conductor of electricity, and burns in air at high red heat with evolution of white clouds of the oxide. It exhibits superplasticity. Neither zinc nor zirconium is ferromagnetic; but ZrZn2 exhibits ferromagnetism at temperatures below 35 K. It has unusual electrical, thermal, optical, and solid-state properties that have not been fully investigated.
Zinc, has a relative Atomic Mass of 65.39, with an atomic number of 30, It is classified as a metal and as such it is a solid. it is silvery in color, has a melting point of 692.78 and a density of 7.14 with a hardness of 2.5. When exposed to a flame, it turns a bluish green color
Compound zinc chloride is a chemical compound where zinc and chlorine atoms are chemically bonded in a fixed ratio. On the other hand, a mixture of zinc and chlorine is a physical combination where zinc and chlorine are simply mixed together without forming any chemical bonds. In the case of a mixture, the components retain their individual properties, whereas in a compound, the properties are different from the individual elements.
Yes, zinc cream contains zinc oxide as its active ingredient. Zinc oxide is widely used in skincare products for its soothing and protective properties.
Dissolving zinc in acid is a chemical property because it involves a chemical reaction between the zinc and the acid, resulting in the formation of new substances (zinc ions and hydrogen gas) with different properties than the original zinc metal.
This answer is based on two assumptions: the question is regarding a United States penny and the term 'properties' is directed toward the metallic composition of the coin. According to the U.S. Mint, a penny is made up of 97.5% zinc and only a mere 2.5% copper, the reddish-brown color metal that gives a penny it's distinct appearance.
Dissolving zinc in water is a chemical process because the zinc atoms react with the water molecules to form zinc ions and release hydrogen gas. This results in a new substance being formed (zinc ions in water), which is a characteristic of a chemical reaction.
Zinc is not a property; it is a substance. Like all substances it has its own set of physical and chemical properties.
Zinc is neither. Zinc is an element it HAS physical and chemical properties. For example Zinc is soft this is a physical property

The hardness and density of zinc are physical properties, as they do not involve any change in the chemical composition of the substance. Changes in physical properties can be observed without altering the chemical identity of the material.
Zinc is not a property at all; it is a substance. Like all substances it has its own set of physical and chemical properties.
A penny is made up of metals - copper and zinc both of which have lustrous physical properties
Mossy zinc is classified as an element because it consists of only one type of atomβzinc. In this case, the atoms are bonded together in a metallic form, which gives mossy zinc its unique physical and chemical properties.

When zinc reacts with acids to produce hydrogen gas, it is a chemical change because new substances are formed (zinc salts and hydrogen gas) with different properties from the original substances.
Examples:- density: 4,74 g/cm3- melting point: 446 oC- crystal structure: tetragonal
