None of the given options (paper airplane, chocolate chip cookie, egg) are suitable for comparing JJ Thomson's model of the atom.
A more appropriate comparison for JJ Thomson's model of the atom would be the "plum pudding model" or the "raisin bread model". In these models, the atom is imagined as a positively charged sphere with negatively charged electrons embedded in it, similar to plums or raisins in a pudding or bread.
JJ Thomson's model of the atom is sometimes compared to a chocolate chip cookie or an egg.
To understand why this comparison is made, we need to first explain JJ Thomson's model of the atom. Thomson proposed the "plum pudding" model of the atom in 1904. According to this model, an atom consists of a positively charged "pudding" with negatively charged electrons embedded in it, much like the chocolate chips in a cookie or the yolk in an egg.
Now, regarding your question about which one is right - it is important to note that JJ Thomson's plum pudding model of the atom is considered incorrect by modern standards. This model did not accurately capture the structure of the atom, and it was eventually replaced by the more accurate atomic models proposed by Ernest Rutherford and Niels Bohr.
Rutherford's model, often called the "planetary model," suggested that almost all the positive charge and mass of the atom is concentrated in a tiny nucleus at the center, while the negatively charged electrons orbit around it, much like planets orbit around the sun.
Bohr's model built upon Rutherford's ideas by introducing the concept of electron shells or energy levels. In this model, electrons occupy specific energy levels around the nucleus, and they can transition between these levels by absorbing or emitting specific amounts of energy.
So, while Thomson's model of the atom is historically significant and was an important step towards our understanding of atomic structure, it is not considered correct based on our current knowledge. The more accurate models of Rutherford and Bohr provide a better description of the arrangement of electrons within an atom.
