Question

question 7. given the particle diagram: key o = atom of an element ● = atom of a different element which type of matter is represented by the particle diagram? a compound an element a homogeneous mixture a heterogeneous mixture

Explanation:

A compound is a substance made up of two or more different types of atoms chemically combined in a fixed ratio. In the particle - diagram, each particle consists of two different types of atoms (represented by different colored circles) bonded together. An element would consist of only one type of atom. A homogeneous mixture would have a more uniform distribution of different substances at a macroscopic level and not just discrete molecules of the same compound. Since all the particles are identical molecules made of two different types of atoms, it is a compound.

Answer:

A. A compound
