Consider the n = 4 shell of the hydrogen atom. Draw the orbital energy diagram, labelling each sub-shell. Now, apply an external magnetic field. Draw the new levels, label each orbital and note any degeneracies.
Consider the Bohr model for the hydrogen atom in its second excited state. How much energy would it take to ionize the atom? 13.6 eV More than 13.6 eV Less than 13.6 eV
4.66 Explain how the Bohr model of the atom accounts for the existence of atomic line spectra. 167 TATI. . 4.72 In order for hydrogen atoms to give off continuous spectra, what would have to be true? 4.56 It always takes energy to remove an electron from an atom, no matter what n shell the electron is in. Also, the higher the n, the more energy an electron starts out with (a) Explain why it takes energy to remove an...
Would bonds in this compound be lonic or covalent (arcie sulfur atom? one)? Explain. e. Draw the Lewis structure. 18. a. What is the likely formula for a compound composed of sodium atoms and one sulfur atom? b. Would this compound be ionic or covalent (circle one)? Explain. c. Why would it be inappropriate to draw a Lewis structure (such as in Model 4) for this compound? 19. Without attempting to draw a Lewis structure, add up the total number...
Consider a ground state calcium atom. Which of the following statements is FALSE? A. The electron configuration of the calcium atom is [Ar]4s^2 B. Two electrons occupy the 3s orbital; a spherically shaped orbital. C. One of the numerous electrons in the 3p orbitals corresponds to the set of quantum numbers: n=1, l=2,ml=0,ms=+1/2 D. The calcium atom has a total of 20 electrons E. The electrons occupying the 1s orbital are lower in ergy than the electrons occupying the 2s...
As written, the following synthesis scheme is flawed. Draw the actual product(s) that would be formed by this scheme. You do not have to consider stereochemistry. You do not have to explicitly draw H atoms. Draw organic products only. If there is more than one major product possible, draw all of them. Separate multiple products using the + sign from the dropdown menu.
Consider this scheme function and explain it
Consider the following Scheme function: (define f (lambda (1st) (cond (null? 1st)) 0) ((number? (car 1st) (+ 1 (f (cdr 1st)))) (else (f (cdr 1st))))) Explain what the function f computes for lists. consider (f '(1 a b 2)) for example.
Is the amount of calcium in bones of a healthy person affected by their average daily calcium intake over time? Explain. What are the major food sources of calcium? Be sure to include some good sources of calcium that are not dairy products. At what age do people achieve peak bone mass? How does calcium intake in the first 3 decades of life affect peak bone mass? What happens to bone mass as adults age (age 30-40 and beyond)? How...
3. Atomic physics of sodium. In the sodium atom, there is a transition between the 3s and 3p atomic states that produces the yellow-orange light seen in many street lamps a. Sodium has 11 protons and 11 electrons with ten of the electrons filling the n =1 and n = 2 levels. Including interactions between the outer electron and the electrons in the underlying shells, should the 3s or the 3p energy level have the highest energy? Use properties of...
can you draw out a separation scheme for this. like how would you
purify this.
