This is a physical property because it describes a characteristic that can be observed without changing the composition of the substance. The ability of white phosphorus to glow in the dark is due to its property of emitting light when exposed to oxygen.
P is the chemical symbol for phosphorus. But you are correct in believing that the two most comman allotropes of phosphorus (red and white phosphorus) exist as P4. a tetrahedral arrangement of 4 phosphorus atoms. Another alloptrope is P2- Diphosphorus, which is highly reactive.
Yes, because a new compound (a new type of molecule, with another chemical composition) is obtained.
Frying an egg is a chemical change in which the protein in the egg white becomes denatured, which causes it to become white and solid. This condition is not reversible by physical means.

Yes, white phosphorus igniting is a physical change because it involves a change in the physical state of the substance (from solid to gas) without altering its chemical composition.
Phosphorous belong to group 15 of the periodic table.
This is a physical property because it describes a characteristic that can be observed without changing the composition of the substance. The ability of white phosphorus to glow in the dark is due to its property of emitting light when exposed to oxygen.
Phosphorous is an element. Here are some sentences.We studied phosphorous in science class today.Phosphorous ignites if you put it into water.Phosphorous is an interesting element.
P is the chemical symbol for phosphorus. But you are correct in believing that the two most comman allotropes of phosphorus (red and white phosphorus) exist as P4. a tetrahedral arrangement of 4 phosphorus atoms. Another alloptrope is P2- Diphosphorus, which is highly reactive.
None of these is a chemical property
Yes, because a new compound (a new type of molecule, with another chemical composition) is obtained.
Frying an egg is a chemical change in which the protein in the egg white becomes denatured, which causes it to become white and solid. This condition is not reversible by physical means.
It has to be smothered or burned up
it white and its soft
Coloring on a white piece of paper is a physical change because the color change is reversible and does not alter the chemical composition of the paper. The paper remains paper even after coloring on it.
