- 20. 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
- 21. Multiple ChoiceThe atom with the largest atomic radius in Group 18 is -ArHeKrRn
- 22. 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
- 23. Multiple ChoiceThe atom with the largest atomic radius in Period 4 (row 4) is -KKrFeFe
- 24. 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
- 25. Multiple ChoiceThe element with the smallest ionization energy in Period 6 is -RnCsOsTm
- 26. Multiple ChoiceAs you move across the periodic table atoms tend to get smaller because, ______________.the atoms have more mass.the atoms have less massthe atoms have more protons.the atoms have less electrons.
- 27. 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.
- 28. Multiple ChoiceWhich has the greater Electronegativity:
