A substance that is formed from atoms with a characteristic set of physical and chemical properties is called what?

A substance that is formed from one type of atoms with a characteristic set of physical and chemical properties is called an element.


How are physical and chemical properties alike?

Physical properties are those that can be observed without changing the identity of the substance. The general properties of matter such as color, density, hardness, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties.

What happends during a chemical change?

in chemical change the chemical properties of an object are changed. for example a paper is burned. both the chemical and physical properties of the paper are change. the paper itself changed into carbon. that is a chemical change. if for example the paper is cut into small pieces that is called physical change because the paper is still a paper but the physical properties of the paper are changed since it became smaller when you cut it.

families of elements with similar chemical properties are called groups.



What is it called when the original and new substances is the same after a chemical change?

It would be called a physical change, and would not be a chemical change at all. In order for a chemical change to occur, the original substances (reactants) must have different physical and chemical properties than the new substances (products).
