Question image

Use your periodic table and identify whether each element will gain or lose electrons.

Reminder- 4 or more gain electrons, 3 or less lose electrons.

Gain electron
Lose electron
Keep the same

​ - together

- outter level of electrons

- valence electrons together

- forms when atoms SHARE electrons with each other

- group of atoms held together by covalent bonds

Draw

Practice drawing a Lewis structure using Boron.

  1. Find the elemental symbol

  2. What group is it in?

  3. How many valence electrons does it have?

  4. Draw those valence electrons on each side.

6

Atoms want a stable valence energy level

  • Write in the chat- how many electrons to make a stable valence energy level?

​Atoms with 4+ valence electrons will GAIN electrons/ atoms

Covalent bonds- between 2 nonmetals (or with a nonmetal and metalloid

​Shows valence electrons
Not good for large molecules

Great to show LARGE molecules
Doesn't show Valence electrons

Draw

Draw a Lewis structure for Neon-

  1. Find it on the periodic table

  2. What GROUP is it in?

  3. Draw Neon's symbol

  4. Draw the correct amount of Valence electrons around the symbol

  5. Will it gain electrons, lose electrons, or be unchanged to be stable?

  6. Hit submit when you're done

8

Draw

Draw a Lewis structure for Fluorine. Identify where it would want a Covalent bond.

  1. Find it on the periodic table

  2. What GROUP is it in?

  3. Draw the correct amount of Valence electrons around the symbol

  4. Identify where a covalent bond would form

  5. Hit submit when you're done

9

  1. Draw Lewis models of each element.

  2. Identify the electrons that will pair up and share.

    Do this until all electrons are paired

  3. Redraw the full molecule

Write in your notes:
