Use the periodic table to answer the following question: what are the periodic trends of ionic radii? check all that apply. ionic radii tend to increase down a group. ionic radii tend to decrease across a period. anionic radii tend to increase across a period. cationic radii tend to decrease across a period. ionic radii increase when switching from cations to anions in a period.

1.Ionic radii tend to increase down a group.

4.Cationic radii tend to decrease across a period.

5. Ionic radii increase when switching from cations to anions in a period.

Step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
