Which two elements would NOT be capable of forming an ionic
bond?

a phosphorus and chlorine
b barium and nitrogen
c iodine and sodium
d. calcium and oxygen
// NOT C//

Tt is not possible with phosphorus and chlorine for the formation of an ionic bond. Hence, option (a) is correct.

The ionic bonds are the special chemical bonds formed by the sharing of electrons. Phosphorus and chlorine are the two groups of elements that would not be capable of forming an ionic bond.

Ionic bonds occurs between a metal and a non-metal to produce an electrovalent compound.

Moreover, phosphorus and chlorine are non-metals.

Thus, we can conclude that it is not possible with phosphorus and chlorine for the formation of an ionic bond.

a phosphorus and chlorine

Explanation:

Phosphorus and chlorine are the two groups of elements that would not be capable of forming an ionic bond.

Ionic bonds occurs between a metal and a non-metal to produce an electrovalent compound.

Phosphorus and chlorine are non-metals.

This is not possible with phosphorus and chlorine.

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.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
