The effective magnetic moment of SC^(3+) is zero. The oxidation state of 3+ indicates that Scandium which has an electronic configuration of 1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 3d^1, 4s^2 …

Oxygen, therefore, has two unpaired electrons which can bond with the two hydrogen atoms. In order to obtain maximum separation of the electron orbitals from the 3 atoms, bonding is …

Explanation: Well, the one I always made was confusing convex with concave. Convex is the one that sorta looks like an almond. When drawing ray diagrams, confusing these two will definitely …

Making use of one of Bohr’s key hypotheses quantization of angular momentum that "the angular momentum of the electron vecL in allowed states takes only integral values of reduced …

The Bohr model applies only to a hydrogen atom or to ions that contain only one electron (hydrogen-like ions). To get a hydrogen-like ion, we must remove all but one of the electrons …

Consider the diagram: We can use trigonometry and identities on right triangles to find: beta=90^@-39^@= 51^@ 150=csin (39^@) so that: c=150/sin (39^@)=238"ft" a=c cos …

The energy of the nth Bohr orbit for a hydrogen atom, which has Z = 1, is given by the equation En = E1 n2, where E1 - the energy of the 1st Bohr orbit, equal to -1312 kJ/mol; n - the energy …

I tried this: Consider the following (simplified) diagram: Plate 1 is moving and entering below plate 2 (melting in the process); plate 2, pushed upward, fractures near the bend allowing magma to …

What is the difference between an orbit in Bohr's model of the atom and an orbital in the quantum mechanical view of the atom? How is Thomson's model of an atom different from Dalton's …

The ionization potential of an atom is defined as the energy required to completely remove an electron . using Bohr's theory , calculate the ionization potential of the hydrogen atom? What's …
