Which of the following statement is NOT correct regarding Rutherford’s nuclear model of an atom? |
The size of the nucleus is very large as compared to the size of the atom. The electrons revolve around the nucleus in circular paths. There is a positively charged centre in an atom called the nucleus. Nearly all the mass of an atom resides in the nucleus. |
The size of the nucleus is very large as compared to the size of the atom. |
The correct answer is option 1. The size of the nucleus is very large as compared to the size of the atom. The statement that is NOT correct regarding Rutherford's nuclear model of an atom is: The size of the nucleus is very large as compared to the size of the atom. Here's why: Rutherford's model described the atom as having a positively charged nucleus at its center, containing almost all the mass of the atom. This nucleus was extremely small compared to the vastly larger empty space around it where the electrons orbited. The incorrect statement implies the opposite, suggesting a large and dominant nucleus compared to the rest of the atom, which contradicts Rutherford's key observation and the actual size comparison of the nucleus and the atom. Therefore, while the other statements accurately reflect the key features of Rutherford's model, the statement about the large size of the nucleus is incorrect. |
