What happens when the positively charged alpha particle directly hits the positively charged?

What happens when the positively charged alpha particle directly hits the positively charged?

Occasionally a positively charged alpha particle will come close to one of these dense atomic centers, which are also positively charged. The collision and the repulsion cause the alpha particle to “bounce” backwards and move on a very different path.

What happens when positive alpha particles get close to the nucleus?

When a (positive) alpha particle approached sufficiently close to the nucleus, it was repelled strongly enough to rebound at high angles. The small size of the nucleus explained the small number of alpha particles that were repelled in this way.

Are alpha particles deflected by positive charges?

The atom being mostly empty space. A small number of alpha particles were deflected by large angles (> 4°) as they passed through the foil. There is a concentration of positive charge in the atom. Like charges repel, so the positive alpha particles were being repelled by positive charges.

What happens to a positively charged particle when it goes near the nucleus of an atom?

A proton is a positively charged particle located in the nucleus of an atom. If an atom has an equal number of protons and electrons, its net charge is 0. If it gains an extra electron, it becomes negatively charged and is known as an anion.

Why do alpha particles have a + 2 charge?

Due to the positively charged nucleus of the gold atoms. Alpha particles are are positively charges particles that are made up of 2 protons, 2 neutrons and zero electrons. Due to the fact that protons have a +1 charge and neutrons hold no charge, this would give the particle a +2 charge over all.

What happens to an alpha particle that gets close to the nucleus?

By far the vast majority of alpha particles will be deflected. But if one comes at just the right direction and with high enough kinetic energy, it will get so close to the nucleus that the nuclear force (a strong but short range force) will overcome the repulsion and pull it in.

Why does the alpha particle fly through the foil?

This is due to the fact that like charges repel each other. As the positively charged alpha particle would fly through the foil it would come in proximity with the positively charge nucleus of the atom.

Why are alpha particles deflected by the Rutherford’s?

Due to the fact that protons have a +1 charge and neutrons hold no charge, this would give the particle a +2 charge over all. Originally Rutherford thought that the particles would fly straight through the foil. However, he found that the particles path would be shifted or deflected when passing through the foil.
