a group of students are performing an experiment in class using collision carts on a track. A 5.0 kg cart moving to the right at 4.0 m/s hits a 7.0 kg cart moving to the left at 6.0 m/s. immediately after the collision, the 7.0 kg cart moves to the right at 3.0 m/s. what is the velocity of the 5.0 kg cart after the collision?

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.
