Question

Part A: When two hydrogen atoms approach one another, a covalent bond is formed due to the overlap of the 1s orbital of each hydrogen atom. The process by which a covalent bond is formed is explained with the help of the graph of potential energy versus the distance between the two atoms. Identify which of the following statements are correct. Check all that apply.

Check all that apply.

1.When the potential energy is zero, a covalent bond is formed.

2.When two hydrogen atoms that are far apart approach each other, the potential energy decreases.

3.When the distance between two hydrogen atoms is 0.74 Å, a covalent bond is formed.

4.When two hydrogen atoms are very far apart, the potential energy approaches zero.

5.At a distance of 0.50 Å the potential energy is less than that at 0.74 Å.

Part B: The Atomic Orbital of two iodine atoms combine to form the diatomic I2 molecule. Use the periodic table to determine the atomic orbital that overlap to form the I2 molecule and the symbol of the noble gas that has the same electron configuration as the eelectron configuration of each bonded iodine atom.
