How To Make Chemical Bonds

Question 1

How are chemical bonds made?

Answer 1

When atoms join with other atoms when their valence electrons enter a “relationship.”

Question 2

How does the relationship between atoms work?

Answer 2

Atoms may decide to share valence electrons or give and take valence electrons

Question 3

Name the 2 types of bonds atoms can make with other atoms

Answer 3

1. Covalent bonds

2. ionic bonds

Question 4

What is the main difference between covalent and ionic bonds?

Answer 4

1. For covalent bonds 2 non-metal atoms share their valence electrons
2. For ionic bonds atoms don’t share electrons, they transfer or take electrons from one atom to another

Question 5

What is a molecule? And what type of bond does it have and why?

Answer 5

A molecule is when 2 or more atoms share electrons in a chemical bond.

The chemical bond is a covalent one because the shells of the 2 or more atoms overlap and the valence electrons go back and forth between the two atoms to make a molescule.

Question 6

What is a formula unit? And what type of bond does it have and why?

Answer 6

When 2 atoms make ions and those ions are attracted to each other (positive (metal) and negative (non-metal) charges like Na+ and CI-) by electrostatic forces to create a 3D lattice structure.

Question 7

How do metals and non-metals form ions?

Answer 7

Metals tend to lose electrons to fill their shells (forms a +ion) and non-metals tend to gain electrons to fill their shells (forms a -ion)

Question 8

Describe the process of ionic bonds giving and receiving electrons

Answer 8

1. A metal atom gives up an electron giving itself a + charge
2. A non-metal atom accepts the electron giving itself a - charge
3. A bond is formed by the electrostatic attraction between the + and - ions

Question 9

Using 2 elements, how do you figure out which bond is made?

Answer 9

When Carbon and Oxygen bond, it is a covalent bond and they will share electrons because they are both non-metal.

When Sodium and Oxygen bond, it is an ionic bond because Sodium is a metal and Oxygen is a non-metal. Sodium will give its valence electrons to Oxygen so it will have a + charge and Oxygen will accept the electrons so it will have a - charge. The attraction between the positive and the negative is what bonds Sodium Oxygen together.
