There are two elements in the transition metal series rm Sc through rm Zn that have four unpaired electrons in their 2 plus ions?
Cr and Fe have four unpaired electrons in their 2 plus ions.
What.........Fe2O3 is named iron (III) oxide because it contains . a. three unpaired electrons c. three iron atoms b. Fe3 plus ions d. O3 plus ions?
b. Fe3 plus ions
What is coluured ion?
colour is the result of electron transitions.many complex ions of transition metals are coloured.Ti(H2O)63+ >> a complex with 1 d-electron - this has a red-purple colour.Cr(NH3)63+ >> a complex with 3 d-electrons - this has a purple colour.Ni(H2O)62+ >> a complex with 8 d-electrons - this has a green colour.Zn(NH3)42+ >> a complex with 10 d-electrons - this one has no colour and has no empty d-orbitals.
Are complex ions soluble?
Some complex ions are soluble in water, some are insoluble.
How you find subatomic particles for ions and isotopes?
Subatomic particles are protons, neutrons and electrons.

What are Ions that are deficient in electrons?
Ions that are deficient in electrons are
How many unpaired electrons in the atom silicon in ground state?
Two. The ground state configuration of Sulfur is [Ne] 3s23p4. According to Hund's rule, the p orbitals must fill up separately first. This results in the first 3 electrons going into separate orbitals, and the fourth then doubles up with the first, leaving the other two p orbitals with unpaired electrons.
Why is magnesium a paramagnetic material?
No Response: Actually that is not true as it is listed as one of the Pauli-paramagnetic metals. For a list of paramagnetic metals go here: http://hyperphysics.phy-astr.gsu.edu/Hbase/tables/magprop.html You can find out more about paramagnetism at: http://en.wikipedia.org/wiki/Paramagnetism
Ions may be described as simple or complex?
In chemistry are known simple ions but also complex ions.
Which ions does not have 18 electrons?
Ions with 18 electrons are exceptions (ex.: Cl-).

What happens to electrons as they are transported along the the electron transport chain?
The electrons are transported through a series of carrier proteins via simultaneous oxidation-reduction reactions. The carriers harvest energy from these electrons to pump H+ ions across the inner mitochondrial membrane. When the electrons reach the very end of the chain i.e. complex 4, they are transferred to Oxygen atoms to form O2- ions. O2- ions then combine with H+ ions in the mitochondrial matrix to form H2O.
Are complex ions soluble?
Some complex ions are soluble in water, some are insoluble.
How you find subatomic particles for ions and isotopes?
Subatomic particles are protons, neutrons and electrons.
How do you find the charge of an atom with 7 valence electrons?
The halogens, group 17, have 7 valence electrons. When they form ions, they gain 1 more valence electron and become ions with a charge of 1-.
