Ionic vs covalant

Covalent Compounds HAVE a positive (+) or negative (-) charge

• True

• False

The correct name for NaCl is...

• Sodium Chlorine
• Sodium Chloride
• Nickel Chloride
• Sodium Choroxide 

Why does K become positive when it bonds to Cl to form KCl?

• Because it loses an electron to have a full valence shell 
• Because it gains an electron to have 2 valence electrons
• Because it loses an electron to become negatively charged
• Because Cl gives away its 7 electrons to Na to form an equal charge

The octet rule means that all valence shells want to have the number...... 

• 1

• 16

All atoms/elements bond in order to ....

• Have a full valence shell
• Give away electrons or take electrons
• Only share electrons
• To create electrical currents for human use
