Match the following terms with the correct definition. 1. covalent bond 2. ionic bond 3. metallic bond 4. mineral 5. Van der Waals Bond

1. chemical bond where atoms share electrons in their outer-most shell 2. chemical bond in which there is a transfer of electrons between atoms 3. chemical bond in which atoms are held together by the free moving of electrons 4. naturally occurring, in organic, crystalline solid that has a narrowly defined chemical composition and has characteristic physical properties 5. a weak chemical bond where atoms are "attracted" to each other

1. isolated 2. single chain 3. double chain 4. sheet 5. framework

1. olivine 1. pyroxene 1. biotite 2. quartz 2. muscovite 2. feldspar

Match the letter in the drawing with the correct label for the item it is indicating. 1. A 2. B 3. C

1. proton 2. neutron 3. electron

Number the minerals according to their hardness on Moh's Hardness Scale. Recall that 1 is the softest and 10 is the hardest.

5. apatite 3. calcite 2. gypsum 10. diamond 9. corundum 1. talc 7. quartz 4. fluorite 6. orthoclase feldspar 8. topaz

Covalent bonds differ from ionic bonds in that A) ionic bonds arise from electrical attraction between positively and negatively charged ions. B) covalent bonds arise from the sharing of one or more electrons. C) covalent bonds can occur between atoms of the same element. D) ionic bonds arise from electrical attraction between positively and negatively charged ions and covalent bonds arise from the sharing of one or more electrons, only E) All of the above

All of the above

Elements bond together to form molecules because they:

are most stable when their outer electron shell is filled.

Ionic bonds occur when electrons:

are transferred between atoms.
