Chapter 2: Problem 101

The first atoms of seaborgium (Sg) were identified in 1974 . The longest-lived isotope of Sg has a mass number of 266 . (a) How many protons, electrons, and neutrons are in an \({ }^{266}\) Sg atom? (b) Atoms of Sg are very unstable, and it is therefore difficult to study this element's properties. Based on the position of \(\mathrm{Sg}\) in the periodic table, what element should it most closely resemble in its chemical properties?

Short Answer

Expert verified
(a) In a \(^{266}\)Sg atom, there are 106 protons, 106 electrons, and 160 neutrons. (b) Based on its position in the periodic table, Seaborgium (Sg) should most closely resemble Tungsten (W) in its chemical properties.

Step by step solution

01

Find the number of protons, electrons, and neutrons in seaborgium (Sg) atom with mass number 266

To find the number of protons, electrons, and neutrons in an atom, we need to know the atomic number, the atomic mass, and the mass number of the element. For seaborgium (Sg), you can find its atomic number in the periodic table, which is 106. The number of protons is equal to the atomic number: \(106\). The number of electrons in a neutral atom is equal to the number of protons: \(106\). The number of neutrons is given by subtracting the number of protons from the mass number: \(266 - 106 = 160\).
02

Identify the element in the periodic table that Sg most closely resembles in its chemical properties

Seaborgium (Sg) is in the d-block of the periodic table and belongs to Group 6. The elements in the same group share similar chemical properties because they have the same number of valence electrons in their outer shell. Other elements in Group 6 include Chromium (Cr), Molybdenum (Mo), and Tungsten (W). Based on its position in the periodic table, Seaborgium (Sg) should most closely resemble Tungsten (W) in its chemical properties. This is because Tungsten is the element in Group 6 that is closest to Seaborgium in terms of atomic number and is the heaviest stable element in the group.

What fraction of the \(\alpha\) particles in Rutherford's gold foil experiment are scattered at large angles? Assume the gold foil is two layers thick, as shown in Figure \(2.9,\) and that the approximate diameters of a gold atom and its nucleus are 270 \(\mathrm{pm}\) and \(1.0 \times 10^{-2} \mathrm{pm}\), respectively. Assume that the gold nuclei in each layer are offset from each other.
