Revolt · Accepted Answer

increases.

Question 5

Electronegativity down a group:

Revolt · Accepted Answer

decreases.

Question 6

Use the periodic table to answer the following question:What are the periodic trends of ionic radii? Check all that apply.

Revolt · Accepted Answer

Ionic radii tend to increase down a group.; Cationic radii tend to decrease across a period.; Ionic radii increase when switching from cations to anions in a period.

Question 7

Why are the trends and exceptions to the trends in ionization energy observed? Check all that apply.

Revolt · Accepted Answer

Ionization energy tends to increase across a period because the nuclear charge increases.; Ionization energy tends to increase across a period because electrons are added to the same main energy level.; The ionization energies of elements in Group 13 tend to be lower than the elements in Group 2 because the full s orbital shields the electron in the p orbital from the nucleus.

Question 8

Use the periodic table to select the element from the drop-down menu that has the correct relative electronegativity.Mg > Be AlCa
