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.

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
