Intro Ionic bonding

How can you use the periodic table to determine valence electrons

• You can use the period number

• You can use the atomic number

• You can use the group number

How many valence electrons does Ca have?

• 4

• 20

• 2

How many valence electrons does S have?

• 16

• 6

• 7

How many valence electrons does O (oxygen) have?

• 16

• 6

• 8

What the lewis Dot structure for O

• 
• 

What is the correct lewis dot for Be

• 
• 

What is the correct lewis dot structure for B?

• 
• 

What are the correct rules for drawing a lewis dot structure? (select all that are true)

• You can double up the electrons fromt he beginning

• It only shows the valence electrons

• Only 2 electrons can go on each side of the element symbol

• You have to put one electron on all side before doubling up.

What's the correct lewis dot structure for Mg

• 
• 

What 2 types of atoms are in a ionic bond?

• Metal and metal

• Nonmetal and metal

• Nonmetal and nonmetal
