When you remove your wool suit from the dry cleaners garment bag the bag becomes positively charged explain how this occurs?
The physical act of separating the bag from the suit mechanically strips electrons off the bag. The electrons remain on the suit leaving it negatively charged whereas some of the atoms that are part of the bag are now missing their electrons and hence the bag has a net postive charge. The magnitude of charge on the bag and suit are equal but opposite as must be the case since charge is conserved.

Explain with suitable diagrams how an electroscope responds when the knob touches a positively charged object?
When the knob of the electroscope touches a positively charged object, electrons from the object are transferred to the electroscope, causing it to become positively charged. This causes the gold leaves to repel each other due to the like charges, spreading apart and indicating the presence of a positive charge on the electroscope. A diagram would show the initial position of the gold leaves close together, then spreading apart when the electroscope becomes positively charged.
Explain Why The Glass Become Positively charged?
Glass can become positively charged through a process called triboelectric charging. When two materials are rubbed together, electrons can be transferred from one material to the other, leading one to become positively charged (loses electrons) and the other negatively charged (gains electrons). Glass tends to lose electrons easily, resulting in a positive charge.
Why glass is charged positively when it is rubbed with dry cloth explain whether glass gains or loses electron when it is charged answer?
When glass is rubbed with a dry cloth, the friction creates a transfer of electrons between the glass and the cloth. Glass loses electrons during this rubbing process and becomes positively charged. This means the glass gives up some of its negatively charged electrons to the cloth, resulting in a net positive charge on the glass.
What was the fatal flaw in ernest Rutherford in 1911 model?
Ernest Rutherford's 1911 model of the atom failed to explain why electrons, which are negatively charged, do not collapse into the positively charged nucleus due to electrostatic forces. This model was unable to account for the stability of the atom.

Define and ion and explain how an ion is formed?
An ion is a charged particle that results from the loss or gain of electrons in an atom. When an atom loses electrons, it becomes positively charged and is called a cation. When an atom gains electrons, it becomes negatively charged and is called an anion. This process of gaining or losing electrons can occur through chemical reactions or through exposure to external influences like electromagnetic fields.
What best describes rutherford's model of the atom?
Rutherford's model of the atom proposed that atoms have a small, dense, positively charged nucleus at the center, surrounded by negatively charged electrons. This model suggested that electrons orbit the nucleus similar to planets orbiting the sun, but it could not explain the stability of atoms or the distribution of electron energies.
What Ions do a sodium atom and a chlorine atoms become when a valence electron is transferred from one to the other?
To answer this question let me just explain ions. If an atom loses an electron, it becomes a positive ion. Example- Oxygen atom loses an electron so now it has 7, O+ If it gains an electron it becomes a negative ion. Example- O- The reason this happens is because when it loses one, there is not enough negative charge to balance with the protons ( + ). Therefore it becomes positively charged. visa-versa

Explain on basis of electron movement the charging of ebonite rod when rubbed with fur?
When an ebonite rod is rubbed with fur, electrons are transferred from the fur to the ebonite rod. This transfer occurs because the materials have different affinities for electrons, with ebonite having a greater tendency to attract electrons. As a result, the ebonite rod becomes negatively charged due to the excess of electrons, while the fur becomes positively charged due to the loss of electrons. This movement of electrons is what generates static electricity in the materials.
Explain why an iron ion is attracted to a sulfide ion but not to a zinc ion?
iron and zinc are metals that tend to lose electrons , thus becoming positively charged. They would repel each other.

Explain how the atom is neutral as a whole?
Atoms are made of protons, neutrons and electrons. Protons are positively charged, electrons negatively charged and neutrons have no charge. Since the number of protons is equal to the number of electrons in any given atom, the overall charge of the atom is neutral (negative charge of one electron cancels the positive charge of one proton) Atoms that are positively charged (cations) have lost one or more electron(s). Atoms that are negatively charged (anions) have gained one or more electrons.
