Why does the electron collide with the nucleus?

now, since their is opposite charge on nucleus as compared to electrons , their must be some force of attraction between the two . this force is responsible for making the electron orbit the nucleus. if electrons emit energy ; they would collide to nucleus within 10−8 sec. This accounts for high instability of atom .

What would happen to the electrons in Rutherford’s model?

The motion of the electrons in the Rutherford model was unstable because, according to classical mechanics and electromagnetic theory, any charged particle moving on a curved path emits electromagnetic radiation; thus, the electrons would lose energy and spiral into the nucleus.

Why did Rutherford expect the particles to pass through?

Assuming a plum pudding model of the atom, Rutherford predicted that the areas of positive charge in the gold atoms would deflect, or bend, the path of all the alpha particles as they passed through.

What does Rutherford’s model explain?

Rutherford’s model shows that an atom is mostly empty space, with electrons orbiting a fixed, positively charged nucleus in set, predictable paths. This model of an atom was developed by Ernest Rutherford, a New Zealand native working at the University of Manchester in England in the early 1900s.

How do electrons move around the nucleus?

The electron travels in circular orbits around the nucleus. Energy is emitted from the atom when the electron jumps from one orbit to another closer to the nucleus.

How did Rutherford find the nucleus?

In 1911, Rutherford, Marsden and Geiger discovered the dense atomic nucleus by bombarding a thin gold sheet with the alpha particles emitted by radium. From this observation, they concluded that almost all the atomic matter was concentrated in a tiny volume situated at the atome center, the atomic nucleus.

How did Rutherford discover the nucleus?

What did Rutherford initially expect?

Rutherford found that a narrow beam of -particles was broadened when it passed through a thin film of mica or metal. He therefore anticipated that virtually all of the -particles would be able to penetrate the metal foil, although they would be scattered slightly by collisions with the atoms through which they passed.

When an electron is captured and becomes part of an atom what happens?

Electron capture is one process that unstable atoms can use to become more stable. During electron capture, an electron in an atom’s inner shell is drawn into the nucleus where it combines with a proton, forming a neutron and a neutrino. The neutrino is ejected from the atom’s nucleus.
