Rutherford’s Atomic Model Formula: Definition, Limitations

Ernest Rutherford developed Rutherford's atomic model . Ernest Rutherford (1871–1937) developed the rules of radioactive decay, found alpha and beta rays, and hypothesized the nuclear structure of the atom. In 1908, he was awarded the Chemistry Nobel Prize.

Rutherford’s Atom Model

• A little volume contains both the mass and positive charge of an atom. He referred to the atom's nucleus.
• According to Rutherford's hypothesis, a negatively charged electron shell surrounds an atom's nucleus. In addition, he claimed that the electrons that orbit the nucleus move in a circular pattern at very high speeds.
• He coined the word orbit to describe their elliptical paths.
• The mass of positively charged particles that make up the nucleus is held together by a strong electrostatic force of attraction that attracts negatively charged and positively charged electrons.

Rutherford’s Observations

• Most of the space in an atom is unoccupied since a significant portion of the -particles blasted toward the gold sheet went through the sheet without deflection.
• Because the gold sheet somewhat deflected some of the alpha particles, the positive charge in an atom is not spread evenly. An atom's positive charge is confined to a relatively tiny volume.
• Only a handful of the alpha particles had deflection angles that were almost 180 degrees, meaning that very few of the alpha particles were deflected back. As a result, the positively charged particles' volume is extremely tiny about the total volume of an atom.
