Which element in the fourth period has the most unpaired electrons?
The element of 4th period of the periodic table having maximum number of unpaired electrons in its ground state is. It is Cr and has configuration 3d54s1 i.e., 6 unpaired electrons.
What is period 4 on the periodic table?
The period 4 transition metals are scandium (Sc), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), and zinc (Zn).
Which atom has most unpaired electrons?

What is the maximum number of electrons in the 4th period?
18
4th period: We know that period four begins with 4s orbital. Once, the electron occupies the 4s orbitals, it jumps to the 3d orbital, and then goes to 4p orbitals. So, the total number of electrons is 2+10+6=18.
How many elements are in 4th period?
18 elements
The fourth period contains 18 elements beginning with potassium and ending with krypton – one element for each of the eighteen groups.
Which Period 4 element has the most metallic properties?
The most metallic element is francium.
Which one of the following has the highest number of unpaired electrons?
As we can see in the d orbital all the electrons are paired, hence it has zero unpaired electrons. Hence, out of the given options $F{e^{2 + }}$ has the most number of unpaired electrons i.e. $4$.
How many electrons in phosphorus are paired?
A neutral phosphorus atom has 15 electrons. Two electrons can go into the 1s subshell, 2 can go into the 2s subshell, and 6 can go into the 2p subshell. That leaves 5 electrons. Of those 5 electrons, 2 can go into the 3s subshell, and the remaining 3 electrons can go into the 3p subshell.
What is the electron configuration of phosphorus?
[Ne] 3s² 3p³
Phosphorus/Electron configuration
