Matter is composed of ultimately of different kinds of atoms Atom the smallest particles of an element that retain the chemical properties of the element. Element matter that consists of only one kind of atom, either individually or combined into larger units. Molecule matter consisting of two or more atoms combined in a definite ratio.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
