Which of the following compounds are examples of covalent bonding?

Select one or more of the following:

Question 5 of 11

1

Fill the blank spaces to complete the text.

Metallic bonding is made of positive ions that are held together by a “sea of electrons” from the outer shells of metal atoms.
The strong forces between the ions and electrons mean metals have very high melting points.

Explanation

Question 6 of 11

1

Giant covalent compounds are ❌ at room temperature. All of the atoms in a giant covalent structure are held together by strong ❌ bonds. These bonds have to be broken, by large amounts of ❌, to melt or boil these substances.

❌ is made up of carbon forming ❌ covalent bonds.

❌ is made of hexagonal rings of carbon, each atom forming ❌ bonds. Each atom contributes an ❌ to the “sea of delocalised electrons”.

Explanation

Question 8 of 11

1

Solids, Liquids and Gases are the three main states of matter.

Which is the correct order of state changes?

Select one of the following:

Solid (evaporation) --> Liquid
Liquid (freezing) --> Gas
Gas (condensation) --> Liquid
Gas (sublimation) --> Solid

1

Fill the blank spaces to complete the text.

Alloys are less than pure metals as they have layers, and so they cannot over each other as easily. The atoms are still held together by metallic bonding.

Explanation

Question 10 of 11

1

Fill the blank spaces to complete the text.

These compounds are usually liquids or at room temperature as the molecules are held together by intermolecular forces of attraction (but the atoms in the compounds are held together internally by strong bonds), so only a small amount of is required to change state. This means simple molecules often have melting and boiling points.
