Use the periodic table and the above figure. Using the data shown in the electron configuration chart, choose the correct electron configuration of carbon.

1s2 2s2 2p2

Use the periodic table and the above figure. How many valence electrons does carbon have?

4

Use the periodic table and the above figure. How many electrons can the p sublevel contain at most?

6

Use the periodic table and the above figure. How many electrons does a carbon atom have?

6

Use the periodic table and the above figure. What is the atomic number of carbon?

6

Use the periodic table and the above figure. What is the first element to have p electrons?

Boron

The carbon bonds in organic compounds are:

Covalent

Study the properties of graphite and diamond. In which would you expect the electrons to be most localized and lacking in mobility, diamond, or graphite?

Diamond

Study the properties of graphite and diamond. Which would make an excellent insulator?

Diamond

Most carbon compounds are formed by exchanging electrons with carbon.

False

The carbon bond arrangements in graphite and diamond are identical.

False

Study the properties of graphite and diamond. Which finds use as an electrical conductor?

Graphite

Valence electrons are found:

In the outer shell of atoms.

Silicon carbide is another network solid with an extensively interlocked structure. Silicon is capable of sharing electrons in the same manner as carbon does with itself in diamond because silicon:

Is in the same group and also has four valence electrons.

Other than carbon being relatively small, what is another reason that carbon can form so many compounds?

The ability to share four electrons.
