If by non rusting you mean it is in the same state it was made in then it wouldn't be part of any change. But if something is rusting it would be a chemical change because the metal is changing composition and it is not the same metal it was in the first place.
cutting a paper is a irreversiable physical change in other words non recurable change.
the physical characteristics of a non metal are not ductile meaning it cant be drawn into wires non mallable meaning it cant be rolled into thin sheets also its poor in luster meaning its not shinny also nonmetals are brittle
Sulpher is non-existent. Sulphur is a non-metal.
calcium is a metalloid as it stands between metal and non metal as it doesn't have all the porperties of metal. calcium oxide is not an element so neither metal or non metal it is a compound
metal and non metal usually combines to form complexes. as the valecy to be satisfied by both does not let them to form simple compounds with each other
what is the physical property of a non-metal
It can oxidize, but it is not normally referred to as 'rusting'.
Any idea is a non example of physical change.
Any idea is a non example of physical change.
metal- shiny non-metal- dull
no because the atomic structure of the atoms in the metal will not chemically change. the free (delocalised) electrons in a metal form non-directional bonds with the atoms. there are also layers of atoms in a metal and these slide over each other and do not break.
Gold is a rare metal that is heavy, malleable, non-rusting, and is used as a source of personal and national wealth.
Assuming you mean by metal a workable metal as opposed to an element classified as metal, it is a hard question to answer because almost all metals can be toxic, in sufficient quantities. Gold and platinum are the two that are inert enough to be non-toxic. As to the others, the least expensive metal that resists oxidation and is relatively non-toxic would be nickel. Tho a percentage of the population shows a contact allergy to nickel.
Any chemical reaction, such as metal rusting, or toast burning are irreversible.
There are no types of metal rust usuallyBut some are considered as so like fast undergoing metal rust,slow undergoing metal rust and non-rusting metalsFast undegoing metal rusts are-iron and copperSlow undergoing are-Nickel oxide.Non-rusting metals- Gold,Platinum,Palladium,Iridium,Rhodium,Lead,Stainless teel,Mercury.
Corrosion, or rusting, is the oxidation of a substance, and therefore a chemical reaction. The most well known corrosion is the rusting of iron, in which the iron is oxidised by oxygen. Both metals and non-metals can therefore undergo corrosion, and it can be by any oxidising agent, and therefore not need be oxygen.
Physical: malleability of the wire Density of the brackets Chemical: they are non toxic
