When a glass rod is rubbed with a material like silk, it gains extra electrons from the silk material. Since electrons have a negative charge, the glass rod becomes positively charged due to an excess of positive protons compared to negative electrons. This positive charge allows the glass rod to exhibit attractive interactions with negatively charged objects.
What else can I help you with?
What forms when atoms lose or gain electrons and become positively or negatively charged they are know as?
When atoms lose or gain electrons and become positively or negatively charged, they form ions. Positively charged ions are called cations, while negatively charged ions are called anions.
A material that loses electrons becomes?
sory but i dont know
What does protons and neutrons have in common?
the protons are positively charged that's how you know if it is a proton or an electron because a electron has a negative charge
How did he know that the nucleus was positively charge?
Ernest Rutherford inferred that the nucleus was positively charged through his famous gold foil experiment in 1909. When he bombarded a thin sheet of gold with alpha particles, most passed through, but a small fraction were deflected at large angles. This unexpected deflection indicated that a dense, positively charged center (the nucleus) was present within the atom, repelling the positively charged alpha particles. This led to the conclusion that the nucleus must contain a positive charge to account for the observed scattering.
What were rutherford's and Thomson's key discoveries about the atom?
Rutherford's key discovery was that the atom has a small, positively charged nucleus and is mostly empty space. Thomson discovered the electron and proposed the "plum pudding" model of the atom, in which electrons were embedded in a positively charged sphere.
How did Rutherford know that nucleus was positively charged?
the nucleus is positively charged because it bounces right off of the gold foil

What kind of materials can be electrically charged when they are rubbed together?
Materials that can become electrically charged when rubbed together are known as insulators. These materials include rubber, glass, plastic, wool, and fur. When rubbed together, the transfer of electrons between the materials creates an imbalance of charges, resulting in one material becoming positively charged and the other negatively charged.
How did Thompson know atoms were neutrally charged?
Early scientists have discovered the negatively charged particles and the positively charged. The atom is neutral because of the presence of equal amounts of both the charges which cancel each other
The term Rutherford gave to the positively charged particles in the nucleus of atoms was?
You should know this...Protons. Next time, just think about the question! (:

When Thomson held a positively charged plate near the cathode ray the beam bent toward the plate What conclusion can be drawn from this observation?
The beam bending towards the positively charged plate indicates that the cathode rays are negatively charged. This observation led Thomson to conclude that the cathode rays are made up of negatively charged particles, which we now know as electrons.
What you know about structure of cation?
A cation has a number of electrons lower than a neutral atom.
What happens when a balloon with a negative charge is brought to the surface of a wall?
i dont know ask your friends at school. if your old, live with it. A Negative Charge or a collection of negative charges will repel other negative charges. A negatively charged balloon will therefore repel those few negative charges in a wall that are capable of moving a little bit. That area of the wall close to the negatively charged balloon will therefore become positively charged. A positively charged wall will attract a negatively charged balloon and the two will stick together.
