Simple covalent bonding a) occurs between two non-metals b) involves the sharing of electrons c) have ions that electrostatically attract each other d) are gases at room temperature 3) Which answer is correct? Simple covalent bonding a) are gases at room temperature b) Have weak bonds between the molecules c) involves shared electrons d) all of the above 4) The pictures shows metallic bonding a) true b) false 5) What type of bonding does this picture show a) ionic b) covalent c) giant covalent d) metallic 6) Which answer best describes why ionic compounds have high melting points? Because... a) they are solids b) they transfer electrons to form ions c) they share electrons creating strong forces d) they have strong electrostatic bonds between ions. e) They are solids at room temperature f) they are brittle 7) Graphite is made entirely of.... a) carbon b) metal c) weak bonds d) simple covalent bonds 8) This picture represents what type of bonding? a) Covalent b) Giant covalent c) Metallic d) Polymer e) Ionic 9) Which answer best describes why ionic bonds are strong? ... a) the sharing of electrons between the ions b) the electrostatic forces between the ions c) the transfer of electrons between the ions d) the high melting points of ionic compounds 10) What type of bonding is shown in this structure? a) covalent b) ionic c) metallic d) giant covalent 11) Which answer gives the best explanation of the statement. Diamonds are strong because a) each hydrogen atom is strongly bonded to every other hydrogen atom. b) each carbon is attached to 4 other carbon atoms c) Silicon and oxygen atoms are strongly bonded to each other. d) each carbon atom is covalently bonds to 4 other Carbon atoms 12) Which answer gives the best description of the reason graphite can conduct electricity a) Each carbon only forms 3 bonds b) Each atom has a free electron c) The delocalised electrons are free to move. d) Each atom has one delocalised electron as Carbon can only form 3 bonds. e) Each atom has one delocalised electron as the carbon allotrope forms 3 covalent bonds giving one delocalised electron 13) Which answer gives the best description to answer the statement?
