A square is shown below. Which expression can be used to find the area, in square units, of the shaded triangle in the square? A square with a side length of 6 units is shown. A diagonal is drawn with one section shaded inside the figure. fraction 1 over 4 ⋅ 6 ⋅ 6 fraction 1 over 2 ⋅ 3 ⋅ 3 fraction 1 over 4 ⋅ 3 ⋅ 3 fraction 1 over 2 ⋅ 6 ⋅ 6

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.

step-by-step explanation:

i believe the answers 600m
