Soon-Yi’s house has a hexagonal window made up of six identical equilateral triangles as pictured below. A triangular section has a height of 14 inches and a base of 16 inches. Which expression is equivalent to the area of one triangular section? One-half times 7 times 8 One-half times 14 times 16 One-sixth times 14 times 16 One-half times 7 times 7

step-by-step explanation:

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.

answer:   c ?
