Bohr diagrams and Lewis symbols

Question 1

Lewis symbols

Does the anion always gain a full octet of valence electrons in a Lewis symbol?

Answer 1

Yes it must always gain a full octet

Question 2

Bohr Diagrams

What is a Bohr diagram? Give me examples of the first group.

Answer 2

A Bohr diagram is a diagram that shows how many protons an element has. (See photo 5)

Question 3

Lewis symbols

What can lewis symbols be used to show?

Answer 3

Lewis symbols can be used to show the formation of an ionic compound

Question 4

Lewis symbols

Does the cation have to loose all of its valence electrons?

Answer 4

Yes! The cation must always loose all of its valence electrons

Question 5

Lewis symbols

Answer 5

See photo 6

Question 6

Lewis symbols

What is a Lewis symbol?

Answer 6

A lewis symbol is a simpler representation of an atom or ion than using a Bohr diagram

Question 7

Lewis symbols

How do you draw a Lewis symbol?

Answer 7

To draw a lewis symbol, first start with the element symbol. Determine the number of valence electrons. Imagine a square box around the symbol. Place dots representing the electrons, one on each side of the box.
