Understanding Molecular Compounds

What is a key characteristic of molecular compounds?

• They involve the sharing of electrons.

• They involve the transfer of electrons.

• They are formed between metals only.

• They are formed between metals and non-metals.

What is the charge of hydrogen in the context of forming water?

• Negative one

• Positive two

• Positive one

• Negative two

How many hydrogen atoms are needed to bond with one oxygen atom to form water?

• Three

• Four

• One

• Two

In a Lewis dot diagram, what does a line between two atoms represent?

• A lone pair of electrons

• An ionic bond

• A shared pair of electrons

• A transfer of electrons

What is the purpose of drawing a Lewis dot diagram?

• To show the ionic bonds in a compound

• To determine the physical state of a compound

• To calculate the molecular weight

• To represent the sharing of electrons in covalent bonds
