The students in a class collected data on the number of minutes per day some kids spend
brushing their teeth. Their data is shown in the dot plot below.
BRUSHING TEETH

Time Brushing (minutes)
Which statement correctly describes these data?
A
The median is 0.5 and the mean is less than the median
B
The median is 0.5 and the mean is greater than the median
The median is 1.5 and the mean is less than the median
D
The median is 1.5 and the mean is greater than the median

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.
