Chemical Bonds Exit Ticket

When does an atom become an ion?

• When it gains or loses electrons and takes on a charge.

• When it is stable because it has a full set of valence electrons.

• When it forms a compound with another atom.

How do covalent bonds form?

• Donating & receiving valence electrons between atoms

• Oppositely charged ions attract each other & form bonds

• Scientists are still not sure how they form

• Sharing valence electrons between atoms

What is the basis of a metallic bond?

• the attraction of neutral metal atoms.
• the attraction between protons and neutrons.
• the attraction between positive metal ions and interlocking electrons.
• the attraction between positive metal ions and free floating electrons.
