The chemistry assignment
يآآآ هلا .. 
يمكن تقولو بدري توك جاي تكتبه 
ويمكن تقولو جزاك الله خير 
بس أنا حاولت احط الموضوع مرتين وكل ما أجي احطه مايزبط 
عموماً هادي الأجوبه :-
Q.1 The sub ****************l with quantum numbers n=4,l=2 is
* 2X2=1=5 =4d
The m1 values for(d) orbital are
*m1 values=5 m= -2,-1,0,1,2
The allowed values of l for the ****************l with n=2 are
* n-1 = 2-1 =1
The allowed values of l for the sub ****************l with n=4 are
*n-1 = 4-1 =3
The number of orbital in a sub ****************l with n=3 and l=1 is
*2X1+1=3
The maximum number of electrons with quantum numbers with n=3 and l=2 is
* 10
When n=2, l can be
*l=1 or 0
When n=2, the possible values for m1 are
* -1,0,1 << البداية من السالب واحد وبعدين الصفر وبعدين الواحد بس صايرين بالعكس جننوني مارضو يعتدلو :103:
The number of electrons with n=4, l=1 is
* e=2(2X1)+1 =6
The quantum number that characterizes the angular shape of an atomic orbital is
 ماعرفت أحــــــــــله
The sub ****************l with n=3 and l=1 is designated as the
*p
The lowest value of n for which a d sub ****************l can occur is n=
*3
__________________________________________________ _______________________
How many possible orbital are there if n= 3

2=3-1
2l+1= 2X2+1=5
How many possible orbital are there in the sub ****************l n= 5, l=4
* 2l+1= 2X4+1=9
How many electrons can be accommodated in the sub ****************l 4f
* n=4 , l=3 e= 2(2l+1)= (2X3)+1 =(2X7)=14 electrons
How many atomic are there for the sub ****************l with n=3, l=2
*orbital=2X2+1=5
What is the symbol representing the set of orbital in the sub ****************l with n=3, l=2
* m= -2,-1,0,1,2
What information does the first three quantum numbers indicate
* It give the properties of a particalr orbital of interest
What does the forth quantum number indicate
* shows that how many electrons can occupy that orbital
What is the shape of the s orbital
*the s orbital shape is spherical
What is the shoe of the P orbital
* the P orbital shape is dum-bell
How many possible orientations are there for the P orbital
* there are
1-px
2-py
3-pz
How many electrons can the first principal level hold
* 2electrons
How many electrons can the second principle energy level hold
* 8electrons
the third principal energy level can hold 18 electrons . What orbital are found in the third principal
* 9orbital
The fourth principal energy level can hold 32 electrons . What orbital are found in the fourth principal energy level
* 16orbital
ملاحظة:
الكلام الي جنبه * يعني الجواب
السموحــه على القصور وان شاء الله الأجوبه تكون صح .. وأهم شي ادا طلع كم جواب غلط لا تسبوني
