2 Jeopardy Categories All About ATOM Study for the final!! Period. We’re Bonding here, aren’t we? A MOLE is a Unit! Number Cruncher Chemistry Matters

3 All About Atom $100 This is the total number of energy levels in the atom and the letter used to symbolize them. BACK 7 energy levels n

4 All About Atom $200 How many protons, neutrons, and electrons are in a selenium ion? BACK Se makes Se -2 ion 34 protons, 45 neutrons, and 36 electrons

5 All About Atom $300 This is the electron configuration for a calcium ion. (Short or long) BACK 1s 2 2s 2 2p 6 3s 2 3p 6 or [Ar]

6 All About Atom $500 Name the concept that holds the nucleus together and overcomes proton repulsion. BACK Nuclear Force

7 All About Atom $1000 When electrons drop from an excited state down to the ground state, this is given off. Give the specific name of energy given off. BACK A photon of light is given off

8 The Periodic Table - $100 The largest percent of the diatomic molecules are found in this group, with this name. BACK Group 7A- Halogens

9 The Periodic Table - $200 Ca would love to bond with someone in this group. What group? BACK Group 6A – The Oxygen Group Ex: CaO

10 The Periodic Table - $300 What does Boron do to achieve a Noble Gas electron configuration? BACK Lose 3 electrons

11 The Periodic Table - $500 This group has the second lowest ionization energy. BACK Group 2 – Alkaline Earth Metals Lowest: Alkali metals

12 The Periodic Table - $1000 Why does atomic size/radii decrease as you move from left to right across a Period? BACK Shielding: # Protons increase, Pulling electrons tighter. e - stay at same energy level

13 We’re Bonding here, aren’t we? - $100 When Ba and N form a compound, this is the correct formula and name: BACK Ba 3 N 2 Barium nitride

14 We’re Bonding here, aren’t we? - $200 This category of elements: - loves to bond with metals - are dull and brittle BACK nonmetals

15 We’re Bonding here, aren’t we? - $300 List the three types of bonds in order of increasing bond strength. BACK Covalent < Metallic < IONIC

16 We’re Bonding here, aren’t we? - $500 This is the Lewis Structure for carbonate, its shape, polarity and bond angle. BACK [C in middle, 3 O’s around] Trigonal planar shape Nonpolar 120°

17 We’re Bonding here, aren’t we? - $1000 This is how an ionic compound is formed from two atoms and what is given off as a result. BACK 1.A metal transfers an electron(s) to a nonmetal forming a cation and an anion. 2.The two ions form a bond through electrostatic attraction and energy is given off.

18 A Mole is a Unit - $100 True or False: A mole of marbles weighs the same as a mole of bricks. BACK FALSE

20 A Mole is a Unit - $300 How do you calculate the number of grams of a substance when given the number of atoms? BACK 1) Divide by Avogadro’s # 2) Multiply by Molar Mass

21 A Mole is a Unit - $500 What is “n”? (not referring to principal energy level) BACK The ratio of the molecular formula to the empirical formula

22 A Mole is a Unit - $1000 (3 minutes time) What is the empirical and molecular formulas for a compound that is: 40.0% C, 6.67% H, and 53.3% O and has a molar mass of 180 g/mol. BACK E.F. is CH 2 O M.F. is C 6 H 12 O 6
