Two different types of atoms have reacted to form a molecule. A close inspection of the atoms reveal that one atom has 11 protons and 10 electrons, while the other has 17 protons and 18 electrons. What type of bond holds them together?

Ionic bond

Ionic bond.

An atom has : 

 no. of protons=no.  of electrons=its atomic number 

The statement : "..one atom has 11 protons and 10 electrons, while the other has 17 protons and 18 electrons." states that there is loss of 1 electron in 1 atom and gain of 1 electron in another atom. That means there is an exchange of electrons between the 2 atoms.

An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions formed by the transfer of electrons. Ionic bonds are formed between a cation(positive ion), which is usually a metal, and an anion(negative ion), which is usually a nonmetal.
