- 1. Multiple ChoiceWhich of the following will have a lower ionization energy than Scandium (Sc)?Helium (He)Titanium (Ti)Calcium (Ca)Magnesium (Mg)
- 2. Multiple ChoiceWhich atom has the largest atomic radius?potassiumrubidiumfranciumcesium
- 3. Multiple ChoiceThe element with the largest electronegativity in the halogens is -AtFClBr
- 4. Multiple ChoiceAs you move down a group, atomic radius increases because -you add more and more neutronsyou add more and more protonsyou add more and more shells (energy levels)you add more atomic mass
- 5. Multiple ChoiceAs you move across the periodic table from left to right, the atomic radius decreases. This is because -the number of protons increases, so attraction to electrons increasesthe number of energy levels increasesthe number of electrons increasesthe atomic mass increases
- 6. Multiple ChoiceThe energy required to remove electrons is the definition of:ElectronegativityAtomic NumberAtomic RadiusIonization
- 7. Multiple ChoiceElectronegativity is...the ability of an atom to attract/ accept electronsthe ability of an atom to lose electronsthe energy required to remove an electron from a specific atomhow easy it is to make friends.
- 8. Multiple ChoiceElectronegativity __________ from left to right within a period and __________ from top to bottom within a group.decreases, increasesincreases, increasesincreases, decreasesstays the same, increases
- 9. Multiple ChoiceWhat elements have zero electronegativity?metalsnonmetalsmetalloidsnoble gases
- 10. Multiple ChoicePut these in order of increasing electronegativity:
Se, S, and OSe < S < OSe < O < SO < S < SeS < Se < O - 11. Multiple ChoiceIonization energy is...the energy required to add an electron to a specific atomhow much energy it takes to remove an electron from an atomthe energy required to shield the outer electrons from the nucleusa measure of the ability of an atom to attract electrons
- 12. Multiple ChoiceWhich of the following pairs of elements have similar propertiesBarium and CalciumSodium and MagnesiumNickel and CopperLithium and Helium
- 13. Multiple ChoiceFrancium (Fr) has the lowest ionization energy in Group 1 because -it has the smallest number of valence electronsit has the greatest atomic massit has the greatest number of protons, so it attracts its electrons the strongestits 1 valence electron is very far from the nucleus, so little energy is needed to remove it
- 14. Multiple Choice
Which of the following will have a higher electronegativity than arsenic (As)?
Oxygen (O)
Neon (Ne)
Antimony (Sb)
Germanium (Ge)
- 15. Multiple ChoiceWhich of the following sequences corresponds to a correct trend in ionization energy?Cl > S > P > AlSr > Ca > Mg > BeRb > K > Na > LiRb > Sr > I > Xe
- 16. Multiple ChoicePut the following in order of increasing ionization energy:Strontium, Aluminum, IndiumStrontium, Indium, AluminumStrontium, Aluminum, IndiumIndium, Aluminum, StrontiumAluminum, Indium, Strontium
- 17. Multiple ChoiceOrder the following in increasing atomic radii:
Ra, Be, Ca, Rb, HRa, Be, Rb, H, CaRb, H, Ca, Be, RaRa, Rb, Ca, Be, HH, Be, Ca, Rb, Ra - 18. Multiple ChoiceThe more protons there are, the ____ .Weaker the pullSmaller the electronsStronger the pullThe bigger the electrons
- 19. Multiple ChoiceWhich one has the largest radius?Lithium (Li, atomic #3)Boron (B, atomic #5)Neon (Ne, atomic #10)Nitrogen (N, atomic #7)
- 20. Multiple Choice
