Use the periodic table to answer the following question:Use the periodic table to explore the ionic radii of elements from Period 3 and Group 17. Consider the elements bromine and chlorine; which element has a larger ionic radius?

chlorine

bromine

B) Bromine

Explanation:

The second question is: Number the elements sodium, magnesium, and potassium in the predicted order of ionic radius from the largest (1) to the smallest (3).

___ sodium

___ magnesium

___ potassium

2

3

1

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
