L) - Jadvalni to’ldiring.
P.S.: Etalon sifatida 12C absolyut massasining 1/12 qismi o‘rniga, jadvalning 1-vertikal qatoridagi qiymatlar etalon qilib olinsin!

G) - Bonus.
1. Xrom atomi shar shaklida bo’lib, atom shar umumiy hajmining 68% ini tashkil etadi. Xrom atomining radiusini (sm) hisoblang.
d = 7,19 g/sm3
A) 1,25*10-8 В) 1,16*10-8
С) 1,35*10-8 D) 1,45*10-8
Yechim: Atomning molyar hajmini topib olamiz. Molyar hajm - 1 mol modda egallagan hajmiga aytiladi. Vm -M / d
Vm = 52g/mol / 7,19 g/sm3= 7,232 sm3.
1) atom uning 68% ini tashkil etadi: 7,232*0,68 = 4,918 sm3
2) bitta atom qancha hajmni egallashini hisoblaymiz.
V(Cr) = 4,918 / 6,02*1023= 8,17*1024 sm3
3) shar hajmini topish formulasi: V = 4/3ПR3. Bundan atomning radiusini hisoblaymiz: R = cube(V / 4/3ПR4).
R(Cr) =cube(8,17-10-24 / 4/3 -3,14) = 1,25-10* sm3
2. Kalsiy atomi shar shaklida bo’lib, atom shar umumiy hajmining 74% ini tashkil etadi. Kalsiy atomining radiusini (sm)
hisoblang. d - 1,55 g/sm3
A) 1,76*10-8 B) 1,65*10-8
C)1,84*10-8 D) 1,96*10-8
3. Magniy atomi shar shaklida bo’lib, atom shar umumiy hajmining 74% ini tashkil etadi. Magniy atomining radiusini (sm)
hisoblang. d - 1,74 g/sm3
А) 1,74*10-8 B) 1,66*10-8
C) 1,46*10-8 D) 1,59*10-8
4. Natriy atomi shar shaklida bo’lib, atom shar umumiy hajmining 68% ini tashkil etadi. Natriy atomining radiusini (sm) hisoblang.
d = 0,97 g/sm3
A) 1,86*10-8 B) 2,73*10-8
C) 1,18*10-8 D) 1,96*10-8
