Q2. Let's try building a one-dimensional crystal lattice from the scratch. Consider an atomic nucleus carrying Z number of protons. Assume that the Coulomb's law holds in this situation. We take many of such nuclei and start placing them at a distance a from each other along a straight line. So, we end up constructing a very long (perhaps, infinite if we could actually have an infinite number of nuclei) straight chain of equi-spaced nuclei. Can you approximately draw the potential energy seen by a free electron in this lattice? A free electron is the one that is free to roam around the lattice, just like the ones in a metal. A good way to attack this problem would be to start by drawing the potential energy of the electron when there was just one nucleus present. After this, you can think that when you bring the nuclei close, they start sensing each others' presence through the electric field.

Consider these statements about an element E in Group SA: . E is essential to life, found in bones, teeth, cell membranes, and energy-storage molecules. It is usually found in living tissue as the anion formed by one E and four O atoms. This anion is also found in many minerals. . E forms pyramidal E, molecules under standard conditions, although these molecules can also fuse with each other to form extended chains of bonded E th atoms. E has the most allotropes of any Group SA element. Among the more common forms, the soft white allotrope is dangerously flammable in air, while the harder red, violet and black allotropes are more stable. At 1 atm and room temperature, the most common form of E is a waxy white solid that glows faintly yellow-green when exposed to air x Oyes 5 Are all of these statements true about the same Group 5A element? no If you said yes, what is E? Enter its chemical symbol: 0
16. Rutherford's experiment with gold estimated the radius of a gold atom to be approximately 1 x 10⁹ cm. Suppose the radius of the nucleus is the same as a basketball. Would the volume of the atom be bigger or smaller than that of a typical domed athletic stadium? Show a little math to support your answer.

Finding atomic mass from isotope mass and natural abundance isotope A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System. Mass-spectroscopic analysis produced the following data on the isotopes of molybdenum in these samples: 97, 'Mo 92 Mo mass relative (amu) abundance 96.91 94.6% Mo 91.91 5.4% Use these measurements to complete the entry for molybdenum in the Periodic Table that would be used on 98765 ALEKS. Be sure your answers have the correct number of significant digits. Explanation 03/5 Caution: your correct answer will have the same format but not necessarily the same numbers as the entry for molybdenum in the Periodic Table we use here on Earth.
