Ionic bond is formed by two opposite type of substances (metal and non-metal) while both covalent or metallic bond is formed by two same type of substances (non-metal and non-metal form covalent bond, metal and metal form metallic bond). Idk if it's true or not.
The correct answer to this open question is the following.
Two examples of how engineers use their knowledge of atoms to create new technologies would be the following.
1.- Engineers can develop new medicines for chronic diseases when they use their knowledge about atoms. With new technologies and different scientific approaches, this new molecular medicine can be more effective in the treatment of terrible diseases that affect humans. The challenge lies in how to make these new medicines more affordable to all kinds of people, not only rich people.
2.- Engineers can also apply their knowledge about atoms to improve the water conditions so more people can have freshwater. Engineers that specialize in the environment can research the properties of water molecules and atoms, so they can develop new ways to purify and improve the quality of water, that we know that water scarcity is a major problem in many parts of the world.
That is True XD
Hope that helps :D
