Hence, we can say that, the size of the nucleus is very much smaller than the whole atom. 4 What is the order of magnitude of the diameter of the earth? C. 5 fm. Rutherford concluded: "The radius of the nucleus must be much smaller than the radius of the atom, and the ratio is about 10 4. The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom.

Use this info and the particle in the box model to make an order of magnitude estimate of the ratio $$\frac{\text{size of atom}}{\text{size of nucleus}}$$. The proton carries a positive charge of 1.6 10 -19 C. In the formula you provide, the mass $m_a$ that appears really refers just to the mass of the particle in the box, which for the atom is the electron. Including the mass of the nucleus would be a bit like including the mass of the box in your formula. the diameter of an atom is typically around 0.1 nm or 1 10 -10 m. The size of an atom can be estimated by measuring the distance between adjacent atoms in a covalent compound.

These protons and neutrons constitute the nucleus of the atom. We know that the nucleus of an atom contains the nucleons, the Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. All these isotopes have 6 protons, but the number of neutrons in them is 6, 7, and 8. Similarly, the box representing the nucleus is provided by the strong nuclear force between protons and neutrons that hold them all in place. The size of an atom is primarily determined by the strength of the attractive force between the nucleus and the electrons. His discovery that they were some 10,000 times smaller than the atoms that con- tained them was due to the remarkable way that alpha particles scatter from metal foils. Approximate size of the nucleus is given by, RA=1. R = R 0 A 1 3 Where R 0 = 1.210 -15 m. From the formula, we can conclude that the volume of the nucleus, which is proportional to R 3, is proportional to A (mass number). Solution.

(b) If atom is represented by planet earth Re=6.4106 m, estimate the size of the nucleus. I used the nm to fm conversion and ratio and got 1/100000 which is basically nucleus/atom or 1 fm / 100000 fm but this wasn't right and I got mixed up here. Step 1: Ratio of the radius of earth and nucleus: If the atom is represented by the planet Earth, ' R e ' = 6. About 5 million hydrogen atoms could fit into a pin head.

The figure of merit for such reactions is $Q^2 = -q \cdot q$, and in the range from about $1$--$8\text{+ GeV}^2$ (the upper limit is not yet experimentally known) the cross-section for this (per target proton) is a constant times the cross-section for the free reaction $p(e,e'p)$. The number for silicon is about 100 picometers: see LeeH (published on 10/22/2007) Follow-up on this answer. neutrons that combine to form atomic nuclei are composed of quarks Including the mass of the nucleus would be a bit like including the mass of the box in your formula. This means that the nucleus has a diameter 10,000 times smaller than the atom.
