Chemistry in Biology Jeopardy Atomic Structure 100- the smallest particle of an element is known as An atom 200- A charged particle is known as An ion 300- What are the 3 subatomic particles and what are their charges? Protons (+), electrons (-), and neutrons (neutral) 400- Which of the subatomic particles are found inside the nucleus? Protons and neutrons 500- What does it mean for an atom to be stable? It has a full outer shell Compounds 100- Why do elements combine with each other to form compounds? In order to fill their shells with enough electrons to become stable 200- A bond that forms when an atom gains or loses electrons is called An ionic bond 300- Which bond is stronger ionic or covalent? Covalent 400- A compound that is made up of all covalent bonds is called Molecule 500- The two types of covalent bonds are Polar and non-polar Water 100- A water molecules are held together by ionic, covalent or hydrogen bonds? Hydrogen 200- The attraction between molecules of the same substance is called Cohesion 300- The meniscus that forms in a graduated cylinder is caused by Adhesion 400- Water has a high heat capacity which means…. Water can absorb large amounts of heat due to the large numbers of hydrogen bonds. 500- Explain how evaporative cooling causes your body temperature to decrease. As water evaporates it pulls heat from your skin to fuel the chemical reaction. Grab Bag 100- A substance with more H+ ions and a pH number of 2 will be a strong acid 200- The atomic mass is equal the total number of which 2 subatomic paricles? Protons and neutrons 300- How many electrons are needed to fill the 3rd ring around the atom? 8 400-In a solution of instant iced tea mix and water which is the solvent? water 500- A base has a large amount of this type of ion OH-
