What causes a pithball to move in an experiment involving a pithball electroscope?
A pithball moves in response to the electrostatic force between the charged object and the pithball. When a charged object is brought close to the pithball, the charges on the object induce a separation of charges in the pithball causing it to become attracted or repelled, leading to its movement.
During a chemical reaction an iron atom become the ion fe2 . what happens to the iron atom?
During the chemical reaction, an iron atom loses two electrons, which causes it to become positively charged and form the Fe²⁺ ion. This loss of electrons typically occurs when iron reacts with more electronegative elements or compounds, allowing it to achieve a more stable electron configuration. As a result, the iron atom transitions from a neutral state to an ionic state, facilitating various chemical interactions.
Why does objects become positively charged if they lose electrons?
When an object loses electrons, it becomes positively charged because it has a deficiency of negatively charged electrons compared to the positive protons in its nucleus. This imbalance of charge causes the object to have an overall positive charge.
What happens to an object with an positive charge and an object with an negative charge are near together?
When a positively charged object and a negatively charged object are near each other, they experience an attractive force due to their opposite charges. This attraction causes them to move closer together, and if they are close enough, they can transfer charge and neutralize each other. As a result, they may eventually come to a state of equilibrium, where their charges balance out, leading to a neutral state.
Why do some charged objects pull each other while other charged objects push each other?
The charged object may induce a separation of charges in the neutral object.The charged object may induce a separation of charges in the neutral object.The charged object may induce a separation of charges in the neutral object.The charged object may induce a separation of charges in the neutral object.
5 What causes an atom to become positively or negatively charged?
Atoms become positively charged when they have a deficit of electrons. Similarly, they become negatively charged when they have a surplus of electrons. Neutral charge, the non-ionized state, is when the number of electrons is the same as the number of protons.
What happens when something is charged by friction?
When something is charged by friction, electrons are transferred between the two objects involved in the frictional contact. This transfer of electrons causes one object to become positively charged (loses electrons) and the other to become negatively charged (gains electrons).
When charging an object by conduction what happened to the charge an object?
Electrons move onto the object, giving it a static charge. Apex ;)
How it is possible for a neutral object to be attracted to a charged object?
A neutral object can be attracted to a charged object through the process of induction. The charged object causes the neutral object's charges to rearrange, creating an attraction between the two objects. This is due to the interaction of electric fields between the charged and neutral objects.
What is charging a neutral object by bringing it close to a charged object called?
Inducing a charge by bringing a neutral object close to a charged object is called electrostatic induction. This process causes the redistribution of charges within the neutral object, resulting in the neutral object acquiring a charge.
What causes plasma to form?
Plasma forms when a gas becomes extremely hot. When this happens, the gas' atoms gain lots of energy. This energy causes the electrons to detach from the nuclei of the gas' atoms. When the negatively charged electrons detach, the positively charged protons and neutral particles called neutrons in the nuclei are left.
What involves the movement of electrons in neutral on objects due to the electric field produced by a charged object?
Electrostatic induction involves the movement of electrons in neutral objects due to the electric field produced by a charged object. When a charged object is brought near a neutral object, the electric field causes the electrons in the neutral object to move, resulting in one side becoming positively charged and the other side becoming negatively charged.
What kind of arrangement causes an atom to become neutral?
an atom becomes neutral if the atom has an equal number of electrons and protons.
What happens when a charged object is brought near a metallic object that is not charged?
When a charged object is brought near a neutral metallic object, the charges in the metallic object redistribute themselves. This causes the charges within the metallic object to separate, with opposite charges being attracted to the charged object. This redistribution of charges induces a temporary charge separation in the metallic object, known as polarization.
Why would an object be neutral?
An object is neutral if it has an equal number of positively charged protons and negatively charged electrons, resulting in a net charge of 0. This balance of charges causes the object to be electrically neutral and not attracted to or repelled by other charged objects.
What happens when you rub a piece of cloth with a polythene rod?
Rubbing a piece of cloth with a polythene rod transfers electrons from one material to the other due to friction. This causes the cloth to become negatively charged and the polythene rod to become positively charged, leading to the attraction between them due to opposite charges.
Why is a neutral object attractred to a charged object?
This is known as electrostatic induction. As charged object (say positive) is brought near by the neutral object the opposite charges i.e. negative would get attracted towards and positive charges would be pushed away. Yet the object is neutral though the charges got separated. Now due to attraction of unlike charges the neutral is attracted towards the charged one.
