Atomic structure and bonding

Question 1

What are the types of interatomic bonds?

Answer 1

1. Ionic
2. Covalent
3. Metallic
4. Van der Waals
5. Hydrogen

Question 2

What are ionic bonds?

Answer 2

1. Cation (positively charged ion) transfers an electron to an anion(negatively charged ion)
2. Strongest bond

Question 3

What are covalent bonds?

Answer 3

1. Sharing of electrons between 2 atoms
2. Almost as strong as ionic bond

Question 4

What are metallic bonds?

Answer 4

Similar to covalent bonding, electrons are shared but are free to move between the entire metal

Question 5

What are Van der Waals bonds?

Answer 5

1.Found between covalent bonds of polymers
2. Weak indirect bonds

Question 6

What are hydrogen bonds?

Answer 6

1. Special case of Van der Waals bonding between hydrogen, O , N, F
2. Considered as weak ionic bonds or strong Van der Waals bonds
