Geckos produce a sticky substance that uses the nuclear strong force to attach to surfaces

Geckos stick to the ceiling using van der waals forces which are lots of weak attractions between neutral molecules.

Geckos use ionic bonds to stick to the ceiling by stealing electrons from the surfaces they stick to

The gecko forms strong covalent bonds between oxygen and hydrogen to stick to the ceiling

How is the movement of electrons different when 2 hydrogen atoms are close together?

What happens if you try to move the atoms very close to each other?

On the periodic table, which group of elements easily gain electrons and become anions?

Which group of elements easily lose electrons and become cations?

Based on what you learned from the simulations, what is the difference between a covalent bond and an ionic bond?

What is unique about the molecular structure of PTFE (Teflon) that makes it "unsticky"?

What is your guess as to why food sticks to pans without teflon?

What is one way to help stop food from sticking to pans?

Why does food stick to stainless steel surfaces

Why do oil and butter help stop food from sticking? Draw a model and explain your hypothesis using evidence from the reading above and your learning of atoms and bonds. Your explanation should be clear and thorough, cite specific evidence, and include atomic level interactions including covalent vs ionic bonds.

Use your understanding of ionic and covalent bonding to model and explain scenarios such as stickiness of materials.
