The modern periodic table is based on the periodic law, which states that physical and chemical propertiesof the elements are a periodic function of their atomic numbers.
Yes this answer is good!
Copper is a chemical element, so it is considered a substance with distinct chemical properties, not a physical property. Its physical properties include being a solid at room temperature, having a distinct color and density, while its chemical properties include its ability to react with other substances and form different compounds.
chemical. when it melts, it doesn't mean it changed into a new substance. it just changed physical states! it is still a metal. physical state is a physical property of any substance, so when it changes physical state, as in changes to liquid, solid or gas, it is still the same substance.
I think you mean "Is burning a paper a physical change?" Burning a paper is not a physical change. It is a chemical change. Because you can't turn the ashes of the paper into a normal paper again. Examples of physical change: Cutting a paper, sharpening a pencil, writing on a paper... Examples of chemical change: Rotten egg, Rusted steel, molded bread...
Because when something freezes, the atoms and molecules don't undergo a chemical change, they go through a physical change. By this, I mean that the individual atoms and molecules lose kinetic energy (energy that makes you move) in order to freeze. There is no chemical change here. Rather, the molecules and atoms are slowing down physically.
If you mean group then your referring to the columns of the periodic table. They will all have the same number of valence electrons and similar chemical and sometimes physical properties.
Distillation is a physical process, not a chemical property. It involves the separation of components in a mixture based on differences in their boiling points.
If you mean a change in chemical identity, that would be a chemical change.

it indicates the physical state at room temperature

what does that mean there are no physical properties in a sentence
No breaking glass is not a chemical reaction, which is what i think you mean. Breaking the glass does not alter the chemical makeup or properties of the glass. Instead breaking glass is a physical reaction because it does alter the size of the glass and its appearance
Melting ice is a physical change rather than a physical property. A physical property describes the characteristics of a substance that can be observed without changing its chemical composition, like color or density. Melting ice involves a change in state from solid to liquid while maintaining the same chemical composition of water.
AU is the chemical symbol for gold on the periodic table.

The Physical Properties of a substance would be … > solid, liquid or gas? > melting point? > boiling point? > color? > density? > odor? > etc, etc, etc ~
Physical properties are things you observe with your eyes during chemical reaction e.g. Salt analysis the choking smell of ammonia u observed with your nose is a physical properties of ammonia
