It is surrounded by the cell membrane and contains the cell&#8217;s chromosomes. The nucleus is responsible for the storage and expression of the cell&#8217;s genetic information.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"History_of_Nucleus_and_Electron\"><\/span>History of Nucleus and Electron<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The history of the nucleus and electron is a long and complicated one. It all started with the discovery of the electron in 1897 by J.J. Thomson. Thomson discovered the electron by using a cathode ray tube. He found that the ray was negatively charged and he named it the electron.<\/p>\n<p>The next big discovery in the history of the nucleus and electron was the discovery of the nucleus in 1911 by Ernest Rutherford. Rutherford found the nucleus by using alpha particles. He found that the alpha particles were being deflected by something and he concluded that there must be a small, dense center to the atom. This center was later named the nucleus.<\/p>\n<p>After the discovery of the nucleus, scientists began to study the structure of the atom in more detail. In 1932, James Chadwick discovered the neutron by using gamma rays. Chadwick found that the gamma rays were being deflected by something and he concluded that there must be a neutral center to the atom. This center was later named the neutron.<\/p>\n<p>The final piece of the puzzle in the history of the nucleus and electron was the development of the quantum theory. The quantum theory explained the behavior of matter on a very small scale. This theory was developed in the early 1900s by Erwin Schr\u00f6dinger, Werner Heisenberg, and Max Born.<\/p>\n<p>With the development of the quantum theory, scientists were finally able to understand the structure of the atom. They found that the atom consisted of a nucleus and electrons<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Facts_about_Nucleus\"><\/span>Facts about Nucleus<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The nucleus is the largest and most complex organelle in a eukaryotic cell. It is a spherical or ovoid structure that is surrounded by a double membrane. The nucleus contains the cell&#8217;s chromosomes, which are made up of DNA and proteins. The DNA is responsible for the genetic information of the cell, while the proteins play a role in gene expression. The nucleus also contains the cell&#8217;s ribosomes, which are responsible for protein synthesis.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Rutherford_Gold_Foil_Experiment\"><\/span>Rutherford Gold Foil Experiment<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In 1911, Rutherford performed an experiment in which he fired a beam of alpha particles (helium nuclei) at a thin piece of gold foil. Most of the alpha particles passed straight through the foil, but a few were deflected. Rutherford used the results of the experiment to develop his model of the atom.<\/p>\n<p>According to Rutherford&#8217;s model, the atom consisted of a small, dense nucleus surrounded by electrons. The nucleus was held together by electrostatic forces, and the electrons orbited around it like planets orbiting around the sun.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Rutherford_Concluded_From_This_Experiment\"><\/span>What Rutherford Concluded From This Experiment<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Rutherford concluded from this experiment that the atom is mostly empty space. He also found that the atom has a small, dense nucleus in the center.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Rutherford_Proposed_The_Following_Nuclear_Model_of_An_Atom_Based_on_His_Experiment\"><\/span>Rutherford Proposed The Following Nuclear Model of An Atom Based on His Experiment<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The Rutherford atomic model is a model of the atom that was proposed by Ernest Rutherford in 1911. The model is based on Rutherford&#8217;s gold foil experiment, in which he bombarded a piece of gold foil with alpha particles and observed the paths of the particles as they passed through the foil.<\/p>\n<p>In the Rutherford model, the atom is composed of a small, dense nucleus surrounded by a diffuse cloud of electrons. The nucleus is composed of protons and neutrons, and the electrons orbit the nucleus in shells.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_the_Size_of_Nucleus\"><\/span>What is the Size of Nucleus?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The nucleus is about 10 micrometers in diameter.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Density_of_Nuclear_Matter\"><\/span>Density of Nuclear Matter<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The density of nuclear matter is about 2.7&#215;1017 kg\/m3.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Introduction to Size of The Nucleus The nucleus is the largest and most dense organelle in a eukaryotic cell.
