Question

Question 1

Answer 1

1. The correct answer is 4. Carbon can bond to 4 other atoms, exponentially increasing its ability to make different molecules.

2. The correct answer is 3. An organic compound (or molecule) is any atom (usually hydrogen) that bonds with carbon.

3.  The correct answer is the third option (8 electrons). Valence electrons in the outer shell are those can form a chemical bond. When (most) atoms have 8 electrons in their outer shell, they are then considered to have maximum stability.

4. The correct answer is 2. These macromolecules all contain carbon and hydrogen, making them organic compounds. 

Answer 2

1 - Carbon atoms can bond with many other kinds of atoms to form very stable molecules. 2 - organic molecules . 3 -  8 (full shell) . 4 - i'd say Carbon and Hydrogen
