Chemical Bonds

What elements generally make an ionic bond ?

• Metal and nonmetal

• 2 or more nonmetals

• 2 or more metals

• 2 elements

An ionic bond is formed when

• Valence electrons are shared.

• Valence electrons surround the cations.

• Valence electrons are transferred between atoms.

• Valence electrons are completely transferred between two metals.

What is a valence electron?

• an electron that is found in the outermost shell of an atom

• an electron found in the innermost shell of an atom

• an electron found in the middle shell

• an electon found in the nucleus

Predict the bond formed between Be and F

• Covalent-bond

• Ionic-bond

• Metallic-bond

• Hydrogen-bond

How do covalent bonds form?

• Donating & receiving valence e- between atoms.
• Opposite slight charges attract each other between compounds.
• Scientists are still not sure how they form.
• Sharing valence e- between atoms.

Why don't noble gases form bonds?

• Noble gases do form bonds

• They all have a full octet

• They only bond with each other

What is a cation? 

• a metal with a negative (-) charge
• a non-metal with a negative (-) charge 
• a metal with a positive (+) charge 
• a non-metal with a positive (+) charge

What is a anion? 

• a metal with a negative (-) charge
• a non-metal with a negative (-) charge 
• a metal with a positive (+) charge 
• a non-metal with a positive (+) charge

Which of these are chemical bonds?

• Hydrogen Bonds

• Ionic Bonds

• Synthetic Bonds

• Covalent Bonds
