A half filled sub-shell is more stable than other partially filled shells. As an example use Chromium. It should by logic have the following:
Sc = [Ar]4s23d1
Ti = [Ar]4s23d2
V = [Ar]4s23d3
Cr should in theory be Cr = [Ar]4s23d4
but it is not. Half filled shells are more stable so the configuration is
Cr = [Ar]4s13d5 two half filled sub levels and then Manganese is
Mn = [Ar]4s23d5 one full and one half filled level.
What else can I help you with?
Which atom is more chemically reactive an atom with a partly filled energy level or an atom with all energy levels completely filled and why?
If all the electron orbitals are filled then the atom is inert. It will not chemically react with anything. If an atom has empty spaces in the outer orbit, it will react with other elements. Electrons from other elements can share positions in the outer orbits.
What is a Adam when it's outer energy level is filled with electrons?
Stable.
What is a partially filled outer electron level makes with?
A completley filled out electron level makes the atom stable
How many electrons does a chemically stable atom have in its outer energy level?
8 electrons
What is the number of the group in which the elements have a filled outer energy level and are stable?
Group 18 aka the Noble Gases / Inert Gases.

How the number of electrons in an energy level affect bond formation?
If the atom is chemically stable it doesnt need to bond, it is chemically stable when the outermost level is completely full of electrons
Which atom is more chemically reactive an atom with a partly filled energy level or an atom with all energy levels completely filled?
the one that is completely filled
What is a Adam when it's outer energy level is filled with electrons?
Stable.
Are the atom is chemically stable when its outer energy level contains all the electrons it can hold?
yes
What is a partially filled outer electron level makes with?
A completley filled out electron level makes the atom stable
How many electrons does a chemically stable atom have in its outer energy level?
8 electrons
What is it called when an atom has an outer energy level is filled with electrons?
it is called complete or completely stable
Which family on periodic table has a filled outer energy level?
The noble gases family in Group 18 have a filled outer energy level, making them very stable and unreactive.
Why is a helium atom stable with only two electrons in its outermost energy level?
helium has completely filled valence orbitals and hence is stable
What is the number of the group in which the elements have a filled outer energy level and are stable?
Group 18 aka the Noble Gases / Inert Gases.
An atom with an incompletely filled outermost energy level is likely to be?
An atom with an incompletely filled outermost energy level is likely to be reactive. This is because atoms tend to gain, lose, or share electrons to achieve a stable outer electron configuration. Atoms with incomplete outermost energy levels are looking to fill or empty their outermost energy level to achieve stability.
