Explain why a suspension is considered a heterogeneous mixture? Classify each of the following substances as an element, a compound, a homogeneous mixture, or a heterogeneous mixture. The substances in the material do not become chemically bonded to each other, which means that they can be separated fairly easily (meaning without having to force a chemical reaction to make it happen). contraction, nerve impulses, and acid-base balance -The ionization energy decreases going down a group, and the ionization energy increases going from left to right across the periodic table. - are extremely tiny particles that make up each type of matter. 2. 3. -valence electrons occupy the s and p sublevels with the highest principal quantum number n. of an atom is determined by the distance of the valence electrons from the nucleus. Physical a. again to identify something as homogeneous or heterogeneous, you need to know the definitions of homogeneous and heterogeneous and some properties of that substance. 2. 7. lead Halo-halo44.
