Gravity on the moon is much weaker than on earth. the expression below can be used to approximate the time in seconds it takes for an object to reach the surface of the moon, when dropped from a height of h meters. to the nearest hundredth of a second, how long would it take for an object dropped from a height of 50 meters to land on the moon? (enter only the number, such as 3.25 without units.)
h(square root)0.82

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.
