When a negatively charged surface approaches a piece of foil, electrons in the foil move to the far side, as they are repelled by the negative charge. This means that the side near the charged surface is positively charged while the far side is negatively charged. Since the electrical force decreases with increasing distance, the attraction experience by the positive near side of the foil will be slightly stronger than the repulsive force of the negative far side. As a result, the foil will experience a net attraction to the charged surface.

What scientist discovered that atoms have a positive charge?
Ernest Rutherford is the scientist who discovered that atoms have a positive charge. Through his gold foil experiment, he found that atoms have a small, positively charged nucleus at their center, surrounded by negatively charged electrons.
Who created the nuclear model of an atom?
Ernest Rutherford is credited with creating the nuclear model of an atom. In 1911, his gold foil experiment demonstrated that atoms have a small, positively charged nucleus surrounded by a cloud of negatively charged electrons. This model laid the foundation for our modern understanding of atomic structure.
When the electroscopes foil leaves are charged and there is contact with the charged plastic rod this is an example of Charge by?
This is an example of charge by conduction. When a charged object, like the plastic rod, comes into contact with a neutral object, like the electroscope's foil leaves, the charge is transferred through direct contact, causing the leaves to become charged as well.
Will foil absorb or reflect light?
Foil will reflect light rather than absorbing it. The shiny surface of foil acts as a mirror, bouncing light rays off of it.
Why alfa particles do not get attracted by the electrons present in the atom when gold foil is bambarded by positively charged helium ions?
Alpha particles are essentially helium nuclei, consisting of two protons and two neutrons, so they carry a double positive charge. The positive charge of the alpha particle and the positive charge of the nucleus repel each other, preventing the alpha particle from being attracted to the electrons surrounding the gold nucleus. This repulsion is what allows the alpha particles to pass through the gold foil without being significantly deflected.
At the beginning of the lab for a versorium is the foil negatively charged positively charged or uncharged?
At the beginning of the lab, the foil is uncharged.
What scientist discovered that atoms have a positive charge?
Ernest Rutherford is the scientist who discovered that atoms have a positive charge. Through his gold foil experiment, he found that atoms have a small, positively charged nucleus at their center, surrounded by negatively charged electrons.
What is Ernest Rutherford's contributions to the atomic sturcture?
Rutherford's famous gold foil experiment disproved Thompson's "plum pudding" model of the atom, and instead suggested a small, central, positively charged region (the nucleus) surrounded by a cloud of negatively charged electrons.
How did the discovery of electrons show that there are also positively charge parts of an atom?
The discovery of electrons through cathode ray experiments by J.J. Thomson demonstrated the existence of negatively charged particles. It raised the question of what positively charged particles balanced the charge in an atom. Subsequent experiments, like the gold foil experiment by Rutherford, led to the discovery of the atomic nucleus containing positively charged protons, thereby revealing the existence of both negatively and positively charged components within an atom.
Does static charge and aluminum foil attract?
Yes, static charge can attract aluminum foil due to the conductivity of the metal. When a charged object is brought close to the foil, the electrons in the foil are repelled to one side, creating an attraction towards the charged object.
What did Ernest Rutherfords gold foil experiment demonstrate about an atom?
Ernest Rutherford's gold foil experiment demonstrated that atoms have a small, dense nucleus at their center that contains positively charged protons. This nucleus is surrounded by mostly empty space where negatively charged electrons are found orbiting. This experiment led to the development of the nuclear model of the atom.
Will a magnet attract aluminium foil?
No, aluminum is a non ferrous. Only ferrous metals can be attracted to a magnet.
Why does plastic stick to your hand?
It's because of Static electricity Human skin is easily positively charged. Plastic wrap is an insulator which means it does not allow electrons to flow from one to the other. Plastic wrap is negatively charged and human skin is positively charged and opposite charges attract. They are forever attracted to each other because human can earth electrons (which means making materials all neutral, equal number of protons and electrons) if the electrons are transffered from a conductor (which allows electrons to move freely from one to the other). e.g aluminium foil. Aluminium foil is a conductor which allows electrons to move freely from one to the other and electrons are transferred to positively charged hands and human earths it, so human is neutral overall and the aluminium foil is positively charged overall. e.g) plastic wrap is an insualtor which does not allow electrons to move freely from one to the other. and electrons are attracted to positively charged hands so therefore, they cling. And because it's an insulator, it will never ever let electrons transfer to human hands! So they will forever repeat :) Hope this helps. Cheers

What is the relationship between a hero and his comic foil?
Charged with sexual tension.
How did Rutherford know that nucleus was positively charged?
the nucleus is positively charged because it bounces right off of the gold foil
Does magnet attracts foil?
Foil is made of aluminum, which, in this case, does not have magnetic properties.
