They are attracted because they have opposite charges.
yes
An electron
Early experiments were based off attraction. The neutron had no charge to attract or repel or to be attracted or repelled. so these experiments could not figure out that there was a neutral particle in the nucleus.
A proton is positively charged; a neutron has no charge and an electron is negatively charged, that is why it is attracted to the atom, which consists of protons.
True. A proton, which has a positive charge, is attracted to an electron, which has a negative charge, due to the electromagnetic force. This attraction is fundamental to the structure of atoms, as protons are found in the nucleus while electrons orbit around it.
Yes, they should because all objects are made of matter and matter consist of three smaller particles which are electron, proton and neutron which respond to electrostatics. So no matter how small the the object is, it just depends on the force applied on it.
Positively charged particles, such as protons, would be attracted to a negatively charged metallic plate. Electrons, which are negatively charged, are repelled by the negative charge and would not be attracted to the plate.
Electrons would be attracted to a proton due to their opposite charges. The positive charge of the proton exerts an attractive force on the negatively charged electron, causing them to be attracted to each other.
There is no specific number of electrons that a proton can attract. For example, in a neutral atom; a proton attracts nearly one electron and there is a higher attraction in anions and lesser number in cations.
The proton will have greater acceleration. This is because the proton has a higher charge to mass ratio than the alpha particle. The proton has a +1 charge, as you know, and the alpha particle has a +2 charge because it has 2 protons in it. But the alpha particle also has a pair of neutrons fuesed to those 2 protons, so it has a 2 to 4 charge to mass ratio. The proton, with its 1 to 1 ratio of charge to mass, will have a greater acceleration in the same electric field.
No. The opposite of an electron is an antielectron or positron, which has exactly the same mass but opposite charge. A proton has opposite charge from that of an electron, but it is about 1836 times more massive.
Electrons will move in response to an electric potential - also known as a voltage. The electron will be attracted towards, or repelled from, one direction, due to this voltage.
