carbon chemistry review

Why can carbon combine with itself to make substances that have very different properties? (ex. graphite and diamond).

• Because of carbon's 4 valence electrons it can form a variety of bonds with other carbons.

• Because carbon is polar it can combine in a variety of ways.

• Because carbon will either give or take 4 electrons so it can form various substances

• Because carbon forms cations it combines in various ways.
