In this lesson, you learned about the properties that distinguish one element from another. In this assignment, you will describe elements, isotopes, and ions.

Element: is a pure substance with one type of atom, and what makes an element unique is its atomic/proton number

isotopes: is two or more species of atoms of a chemical element with the same atomic/proton number.(meaning in I should job has the same element but different neutrons)

ions: is a atom that has lost or gained electrons

Hopefully i could help(this was all from my notes so it’s a bit more simplified!!

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.
