The chemistry assignment

يآآآ هلا .. :119:

يمكن تقولو بدري توك جاي تكتبه :hahahahahah:
ويمكن تقولو جزاك الله خير :cheese:
بس أنا حاولت احط الموضوع مرتين وكل ما أجي احطه مايزبط :Cry111:
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
:017: ماعرفت أحــــــــــله :017:
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
* l=n-1
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 :119:

:119: السموحــه على القصور وان شاء الله الأجوبه تكون صح .. وأهم شي ادا طلع كم جواب غلط لا تسبوني :hahahahahah:
