What is the flow of negatively charged particles through matter also known as?
The flow of negatively charged particles through matter is known as electron current. This refers to the movement of electrons within a material in response to an applied electrical field.
Why is the black rod negatively charged?
The black rod is negatively charged because it has gained extra electrons, which are negatively charged particles, through a process called electron transfer. This excess of electrons makes the rod negatively charged relative to the surrounding environment.
What is the name of moving particles in electricity?
The moving particles in electricity are called electrons. These negatively charged particles flow through conductive materials, creating an electric current.
Why do atoms have no electric charge even through most of there particles have charges?
A neutral atom has equal numbers of positively charged protons and negatively charged electrons.
Who invented the negatively charged particle electron?
The negatively charged particle electron was discovered by J.J. Thomson in 1897 through his experiments with cathode rays. Thomson's experiments led him to propose the existence of the electron as a fundamental subatomic particle.

How can water be negatively charged?
Water can become negatively charged when it gains extra electrons, which are negatively charged particles. This can happen through processes like ionization or interaction with other charged particles.
Why is the black rod negatively charged?
The black rod is negatively charged because it has gained extra electrons, which are negatively charged particles, through a process called electron transfer. This excess of electrons makes the rod negatively charged relative to the surrounding environment.
What carries the current through a liquid?
In a liquid, the current is carried by the movement of charged particles called ions or electrons. Ions can be positively or negatively charged atoms or molecules, while electrons are negatively charged subatomic particles. The flow of these charged particles creates an electric current in the liquid.
What is the name of moving particles in electricity?
The moving particles in electricity are called electrons. These negatively charged particles flow through conductive materials, creating an electric current.
How does an electron exert a force on another charged particle?
An electron exerts a force on another charged particle through the electromagnetic force. This force arises due to the interaction of the electric fields surrounding the charged particles. Like charges repel each other, so electrons (which are negatively charged) repel other negatively charged particles.
Which particles are responsible for the flow of current in conductors physics?
In conductors, the flow of electric current is primarily carried by the movement of electrons. Electrons are negatively charged particles that can move through the material in response to an applied electric field, creating the flow of current.
Why do atoms have no electric charge even through most of there particles have charges?
A neutral atom has equal numbers of positively charged protons and negatively charged electrons.

How can one obtain negatively charged water?
Negatively charged water can be obtained through a process called electrolysis, where an electric current is passed through water to separate it into positively charged hydrogen ions and negatively charged hydroxide ions.
Why do smoke particles become negatively charged when they go through a metal grid?
Smoke particles can become negatively charged when they pass through a metal grid due to the process of electron transfer. As the particles collide with the metal surface, they can gain electrons, leading to a negative charge. This occurs because the grid can act as a source of free electrons that can be transferred to the smoke particles. Consequently, the accumulation of these extra electrons results in the particles acquiring a negative charge.
Who discovered that there are small negatively charged particles inside an atom?
J.J. Thomson discovered the existence of small negatively charged particles, later named electrons, inside an atom through his cathode ray tube experiments in 1897. This discovery laid the foundation for the development of the atomic model.
