If a space heater draws 10 amps from a 120-volt household circuit, and electricity costs 100 per
kilowatt-hour, how much has it cost to run the space heater for 3 hours? Note that a watt-hour is
equal to 1 watt of power used for one hour.
A. $0.12
B. $0.36
C. $1.20
D. $3.60
E. $4.28

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.
