Chemistry Review Part 1

What are the three subatomic particles of an atom?(hint: start with what is in the nucleus of the atom first) particle name protons neutrons electrons particle charge positive neutral negative Complete the short paragraph below with the following words:molecules protons electrons neutrons same patterns The three subatomic particles that make up atoms are protons, neutrons and electrons. All of the same atoms make up elements. Atoms can be arranged as well as definite molecules or repeating crystal patterns. Label the picture. Label a, b, and c, of the atomic structure below with the proper terms.Hint: Look back at #1 electrons neutrons protons Which statement best describes the structure of an atom? protons and electrons grouped together in a random pattern protons and electrons grouped together in an alternating pattern a core of protons and neutrons surrounded by electrons a core of electrons and neutrons surrounded by protons Which of the following best describes the nucleus of a Carbon (C) atom? a collection of electrons and neutrons a collection of protons and neutrons a group of neutrons only a group of protons only True or False: A compound is made up of two or more chemical elements that are chemically combined. true false Use this image to help you with the next question. Which of the images best represents a compound? a b c Use the following words to complete the sentences:heterogeneous chemically homogeneous mixtures When 2 or more elements chemically combine, they form compounds. If elements or compounds physically, they form mixtures. There are two types of mixtures: heterogeneous and homogeneous mixtures. Explain why a substance like Kool-aid or sweet tea is considered a homogeneous mixture. Complete the chart below using the following terms:element mixture compound homogeneous mixture matter matter Homogeneous Mixture Element Compound Mixture
