Gold is a specific chemical substance symbolized on the periodic table of chemical elements as Au with an atomic number of 79. Physical and chemical properties of gold can change depending on its present phase of matter (solid, liquid). Some of its properties include: * Metallic yellow (in its pure state); * Malleable; * Ductile; * Soft; * Shiny; * Oxidized states of -1, 1, 2, 3, 4, 5. Others can be found in more detail at the related links.
What else can I help you with?
Is this a physical or chemical change forming a bar of gold into wire?
Forming a bar of gold into wire is a physical change. This is because the gold is being physically reshaped without undergoing a chemical reaction. The properties and composition of the gold remain the same throughout the process.
Is hammering gold into foil a chemical or physical change?
physical change, because you are changing the physical property of the object. you are causing the change by hammering it. If you were to put some kind of chemical on it and it changed the physical property of the object that would be a chemical change.
Is forming a bar of gold into wire a physical change or a chemical change?
Still a physical change because its still gold and weren't doing anything like making a new element or mixing chemicals with the gold. So its still a physical change.
What happens to the chemical and physical properties of a substance formed in a chemical reaction?
The chemical properties of a substance change during a chemical reaction, meaning the substance undergoes a chemical change and forms new substances with different properties. The physical properties may also change, such as color, texture, or state of matter.
Forming a bar of gold into wire chemical or physical?
When a gold bar is shaped into a wire, the gold's chemical properties do not change. Only the physical appearance changes when gold is changed in shape. Thus, this is an example of a physical change.
Why melting and boiling points are physical properties of gold?
Because gold melted or boiled remain gold, any chemical transformation occur.
Does chemical and physical properties are probably the same?
No. Chemical and physical properties are different.
When do the physical and chemical properties change?
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
Is this a physical or chemical change forming a bar of gold into wire?
Forming a bar of gold into wire is a physical change. This is because the gold is being physically reshaped without undergoing a chemical reaction. The properties and composition of the gold remain the same throughout the process.
Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Is hammering gold into foil a chemical or physical change?

Is forming a bar of gold into wire a physical change or a chemical change?
Still a physical change because its still gold and weren't doing anything like making a new element or mixing chemicals with the gold. So its still a physical change.
Does copper have chemical or physical?
Copper has both chemical and physical properties. Chemical properties refer to how copper reacts with other substances, while physical properties refer to characteristics like its color, density, and conductivity.
Is sour milk a chemical properties or a physical properties?
Chemical property
What happens to the chemical and physical properties of a substance formed in a chemical reaction?
The chemical properties of a substance change during a chemical reaction, meaning the substance undergoes a chemical change and forms new substances with different properties. The physical properties may also change, such as color, texture, or state of matter.
Are fertilizers physical or chemical properties?
chemical
Is a property of matter chemical or physical?
Matter has chemical properties (ex.: chemical reactivity) or physical properties (ex.: thermal conductivity).
