17. Chemical bonds hold compounds together 500 Two properties of covalent bonds. What is covalent bonds melt at relatively low temperatures and stay intact in water? (they also do not conduct electricity when dissolved in water)

18. Substances’ properties depend on their bonds 100 This makes metals easy to form into different shapes. What is electrons move easily among atoms in metals.

19. Substances’ properties depend on their bonds 200 Carbon has this ability because of different bonds. What is carbon can have different forms?

22. Substances’ properties depend on their bonds 500 Two characteristic properties of compounds with metallic bonds. What is metallic bonds make metals melt at high temperatures and conduct electricity? (also, metals can be flattened into thin sheets or drawn into wires, and are shiny)

23. More Chemistry Facts 100 Three types of carbon substances. What are diamond, graphite, and fullerene

24. More Chemistry Facts 200 How do you know that hydrogen is a molecule by looking the diagram on this slide? What is a molecule is a group of atoms joined together by a covalent bond? Since both atoms are the same, they must be joined by covalent bonds. Therefore, it is a molecule.

25. More Chemistry Facts 300 This is how you know sulfur is the negative ion in Pyrite. What is it comes last in the chemical formula?

26. More Chemistry Facts 400 What you know is probably true about methane (CH 3 ) and the elements that make it? It is made of carbon and hydrogen. It has one carbon atom and three hydrogen atoms. It has unique properties it is not like the elements that it is made of.

27. More Chemistry Facts 500 The three types of chemical bonds and how they form. Chemical bonds form when electrons in the electron clouds of two or more atoms interact. Ionic bonds form when atoms transfer electrons. Covalent bonds form when atoms share electron pairs. Covalent bonds form individual molecules. Metallic bonds are bonds in which metal atoms share electrons equally in all directions.
