Round the mixed number to the nearest 1/2. 100 1/3a.100b.100 1/2c.101

B. 100 1/2

Step-by-step explanation:

100 1/3 is = 100.33 which is greater than 100.25 which is the halfway point from 100 to 100 1/2. Since 100.33 is closer to 100 1/2 than 100, we can round up to 100 1/2 because that is the nearest 1/2.

i believe the correct answer is b.

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.
