I WILL GIVE RHE BRAINLIEST ANSWER

A, B

Step-by-step explanation:

Side lengths in cm:

Chloe: 30, 24, 18

Juan: 20, 16, 12

Look at the ratios of the corresponding side lengths:

30/20 = 3/2

24/16 = 3/2

18/12 = 3/2

Since all ratios are equal, by SSS Similarity, the triangles are similar.

A, B

Step-by-step explanation:

the triangles have the same shape and measures

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
