Koryn is building a house. In order to visualize the house, she is building a model. She tapes off two squares with the first square being 3 feet larger than the second square. The total area of the squares is modeled by the equation:

(y+3)^2+y^2=369

a) What is the side length of the smaller square?

b) What is the area of the smaller square?

c) What is the side length of the larger square?

d) What is the area of the larger square?

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.
