1. A chemical bond in an attractive _______________________ that holds atoms together.
2. Chemical bonding is the process of atoms combining to form new __________________________.
3. Matter tends to exist in its ______________________________ energy state.
4. A(n) __________________________ bond is a bond in which one atom donates electrons to another atom.
5. When the number of protons equals the number of electrons an atom has a _________________________
charge.
6. Ions are atoms with a positive or negative _______________________________.
7. _______________________________ is the process of removing electrons from atoms to form ions.
8. Electron_________________________________ is the tendency of an atom to gain electrons when forming
bonds.
9. A bond in which atoms share electrons is called a _________________________ bond.
10. In a(n) ____________________________ bond many electrons are share by many atoms.
11. Metallic bonds are ____________________________________ thus metals are able to be pounded into many
shapes.
12. Ionic compounds have a low _____________________________ in the solid state, and a higher
_________________________(same work) in the molten state.
Indicate whether the following statements are true (T) or false (F). If the statement is false, re-
write the statement to make it true.
1. Chemical bonding is the process of atoms combining to form new substances.
2. Valence electrons are in the innermost energy level.
3. Matter in its lowest energy state tends to be more stable.
4. Particles with a positive or negative charge are called ions.
5. One property common to metals is ductibility.
6. Covalent molecules tend to have higher melting and boiling points compared to ionic compounds.
7. Covalent molecules conduct electricity in all states.
