Explanation:
This man started the development of the periodic table, by arranging elements by atomic mass.
Answer:
As a positively charged object moves toward another positively charged object, their potential energy increases. True
As a negatively charged object moves toward another negatively charged object, their potential energy increases True
Explanation:
When two like charges move towards each other, there is increase in potential energy because the motion is in opposition to the direction if the field. Hence when two negative or two positive charges move towards each other, there is an increase in potential energy.
However, potential energy is inversely related to the distance of separation of the charges.
