Questions and Answers

What is the main purpose of Step 6 in the process described?

To write the charge outside the brackets

To make sure the structure has brackets around it

To determine the number of remaining electrons

To ensure all atoms have a full octet (correct)

If there were not enough electrons to satisfy the octet rule for all atoms, what step would be necessary?

Step 7

Step 5 (correct)

Step 3

Step 4

Why is hydrogen already satisfied without needing any additional electrons?

Hydrogen has a full octet with two electrons

Hydrogen shares electrons with oxygen

Hydrogen can never satisfy the octet rule

Hydrogen only needs one electron to fill its valence shell (correct)

What would be the consequence if the remaining electrons were not placed around oxygen in Step 4?

The structure would not be stable Signup and view all the answers

When would a structure need to go through Step 7 according to the process?

For polyatomic ions Signup and view all the answers

What does the octet rule state?

Atoms want to have a stable electron configuration consisting of eight valence electrons. Signup and view all the answers

Why is hydrogen an exception to the octet rule?

Hydrogen is happy with only two valence electrons. Signup and view all the answers

How does drawing Lewis dot structures for polyatomic ions differ from drawing them for molecules?

For polyatomic ions, you must add or subtract electrons based on the charge of the ion. Signup and view all the answers
