How many unpaired electrons does a neutral
Co atom have?
Step by step
Solved in 2 steps with 1 images
- Suppose that the H2+ ion is excited by light so that an electron moves from a lower-energy to a higher energy MO. Would you expect the excited- state H2+ ion to be stable or to fall apart? Explain.Write out the ground-state electron configurations of Ru2+How many electrons does a Co atom have in its 3d subshell? How many of those electrons are unpaired?
- Pauli exclusion principle specifies that each (1) can hold (2) two electrons, which must have (3) spins. (1) = electron state, (2) = more than, (3) = opposite. (1) = subshell, (2) = more than, (3) = the same. (1) = electron state, (2) = no more than, (3) = opposite. (1) = subshell, (2) = no more than, (3) = opposite.How many 3d electrons are in Fe?For each of the statements below, indicate whether it is true or false and explain your reasoning. (1 sentence ) 1/ It takes more energy to ionize an electron from the 2s orbital than an electron from the 2p orbital in the Li2+ ion. 2/ The electron affinity of the Ne atom is larger than the electron affinity of the F atom. 3/ K* has a larger radius than Ar. 4/ For a diatomic molecule, in which the internuclear axis is the z-axis, the 3dz? orbital cannot mix with the 2px orbital. 5/ The internuclear distance of O2 increases as it takes an additional electron to become O2".
- In the ground state electronic configuration of Co (atomic number 27), how many total shells, subshells and orbitals contain at least one electron, and how many unpaired electrons are present?How many unpaired electrons does N2- have?Do atoms in excited states emit radiation randomly, at any wavelength? Why? What does it mean to say that the hydrogen atom has only certain discrete energy levels available? How do we know this? Why was the quantization of energy levels surprising to scientists when it was first discovered?
- Which of the following is the electron configuration of ground state As atoms? O [Ar]4s?3d104p4 [Ar]4s3d104p4 O [Ar]4s24p63d7 [Ar]4s?3d104p3 O [Ar]3s23d103p3Paramagnetism is the tendency of an atom to be attracted to a magnet. The more unpaired electrons there are, the higher its paramagnetic property. Given that, arrange the following according to increasing paramagnetism: Cr, Cr2+, Cr³+ and explain your answer. Edit View InsertWrite the complete ground-state electron configuration of Cd²+. For multi-digit superscripts or coefficients, use each number in succession.
