Explanation:

1. Separation of charges in an object without touching it is (charging by induction).

2. The work done moving a positive test charge between two points in an electric field divided by the magnitude of the test charge is the electric (potential difference).

3. An electric (conductor) is a material through which charges move about easily. (Charging by conduction) is giving a neutral object a charge by touching it with a charged object.

4. A material through which electrical charges does not move easily is an electrical (insulator).

5. The lines providing a picture of the size and strength of the field around a charged object are called the (electric field lines).

6. The property of the space around a charged object that exerts a force on other charged objects is the (electric field).

7. A device that helps determine charge using pieces of metal foil is an (electroscope).

8. The magnitude of the charge of an electron is the (elementary charge)

the answer for sodium is 0.186

the answer for rubidium is 0.251

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
