Physical Science Ionic & Covalent Bond Quest

Valence electrons are found

• in the innermost orbital of an atom

• in the middle orbital of an atom

• in the outermost orbital of an atom

How do covalent bonds form?

• By donating and receiving valence electrons between atoms.

• Scientists still aren't sure.

• Opposite slight charges attract each atom in the compound.

• Sharing valence electrons between atoms

What kind of bond will form between Hydrogen and Oxygen?

• ionic

• covalent

• metallic

• no bond
