Gain electrons - Study guides, Class notes & Summaries

chemical bond CORRECT ANSWER the force that holds two atoms together Atoms gain stability when CORRECT ANSWER they share electrons and form covalent bonds. The stability of an atom, ion or compound is related to its energy: CORRECT ANSWER lower energy states are more stable Metals and nonmetals gain stability by CORRECT ANSWER transferring electrons (gaining or losing) to form ions that have stable noble-gas electron configurations. Another way atoms can gain stability is CORRECT ANS...

AP BIOLOGY UNIT 2 TEST QUESTIONS WITH VERIFIED ANSWERS Compare and contrast P2 and P1. Photosystem II begins , which absorbs wavelengths at a wavelength of 680 nm. Here, energy is absorbed and passed along until it reaches P680 chlorophyll. When this chlorophyll is excited, it sends its electrons to the primary electron acceptor. Electrons are taken from H2O and passed to P680 to replace the electrons given to the primary acceptor. This forces O2 to form. The electrons are passed to ph...

How do catalysts and inhibitors affect reaction rates? How is ∆G affected by enzymes? correct answers catalysts increase reaction rates; inhibitors decrease them. ∆G is not affected by enzymes Name 3 ways to determine if something has been oxidized or reduced. correct answers oxidation= gain of oxygen, loss of hydrogen, loss of electrons reduction=loss of oxygen, gain of hydrogen, gain of electrons Name cellular location and end products per glucose for the following: glycolysis, pyru...

Covalent bonds: Covalent compounds are formed when nonmetals share valence electrons forming a covalent bond. Ionic bonds: Ionic compounds are formed when metal atoms transfer electrons to nonmetal atoms resulting in the formation of ionic bonds. Covalent bond: Share electrons with nonmetal to form a covalent bond Ionic bond: transfer electrons from metal to nonmetal to form covalent bond - electron donor and an electron acceptor (cation and anion) Covalent: water, H2O 2 H atoms + 1 O ato...

Edexcel iGCSE Chemistry, question and answer with rated solution Experiment for Diffusion? 1) HCl placed at one end of the test tube, ammonia solution at the other. 2) Where they meet, a ring of Ammonium Chloride appears. 3) The diagram shows that the ammonia is closer to the ring, showing that ammonia must have travelled faster, showing it's a lighter gas. Experiment for Dilution? 1) Put a coloured substance in a solvent e.g food colouring in water. 2) Over the time, the colour le...
