Write the electron configuration (full, and in core notation) for the following ions: 1.-1Br +3 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6 [Kr], [Ar] 3d 10 4s 2 4p 6 2. Sr +2 8. 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6 4s
The orbital diagram for a ground-state oxygen atom is. A. phosphorus B. nitrogen C. arsenic D. vanadium E. none of these. 39. How many unpaired electrons does a ground-state atom of sulfur have?
Orbital diagrams are a visual way to show where the electrons are located within an atom. Orbital diagrams must follow 3 rules: The Aufbau principle, the Pau...
When this ion bonds to a metal atom, the two N atoms, and four of the O atoms, are used. [Fe(EDTA)] 2-In this complex, a single EDTA 4-ion forms 6 bonds to the Fe atom (i.e., 2 Fe-N bonds and 4 Fe-O bonds). The coordination number of 6 results in an octahedral structure.
The chart of nitrogen states is similar to the chart in the last section. Note that the chart method is clearly easier to use in this case. Our prediction of the ground state is again correct and a few space symmetric states end up a few eV higher than the ground state.
The wave function of the ground state of a particle in a one-dimensional box is a half-period sine wave, which goes to zero at the two edges of the well.The energy of the particle is given by , where h is the Planck constant, m is the mass of the particle, n is the energy state (n = 1 corresponds to the ground-state energy), and L is the width of the well.
Aufbau Principle - electrons fill orbitals starting at the lowest available energy state before filling higher states (1s before 2s). Pauli Exclusion Principle. An orbital can hold 0, 1, or 2 electrons only, and if there are two electrons in the orbital, they must have opposite (paired) spins. When we draw electrons, we use up and down arrows.
