Isotopes, isotones, and isobars

my presentatation

1. ISOTOPES, ISOTONES, AND ISOBARS evina

2. ISOTOPES Isotope is a group of nuclides that own sum of proton is same but sum of neutron is different. Examples: Isotope : 4 Be 7 ; 4 Be 9 ; 4 Be 10 Isotope : 12 Mg 24 ; 12 Mg 25 ; 12 Mg 26 Isotope : 20 Ca 40 ; 20 Ca 41 ; 20 Ca 42 ; 20 Ca 43 ; 20 Ca 44 ; 20 Ca 45 ; 20 Ca 46 ; 20 Ca 47 ; 20 Ca 48 Isotope : 38 Sr 82 ; 38 Sr 83 ; 38 Sr 84 ; 38 Sr 85 ; 38 Sr 86 ; 38 Sr 87 ; 38 Sr 88 ; 38 Sr 89 ; 38 Sr 90 Isotope : 56 Ba 130 ; 56 Ba 132 ; 56 Ba 133 ; 56 Ba 134 ; 56 Ba 135 ; 56 Ba 136 ; 56 Ba 137 ; 56 Ba 138

3. ISOTONES Isoton is a group of nuclides that has sum of neutron is same but sum of proton is different. Examples : 31 P15 with 32  C  1 6

4. ISOBARS Isobar is a group of nuclides that has sum of proton and neutron are same but sum of each proton and neutron is different. Examples : 12 C 6   with   12  C  7

5. EXERCISES Isotope : 4 Be 7 ; 4 Be 9 ; 4 Be 10 What the element is isobar for 4 Be 7 ? What the element is isoton for 4 Be 10 ?

6. ANSWER : 4 Be 7 Isobar of 4 Be 7 are 3 Li 7 2. 4 Be 10 isotone for 4 Be 10 are 6 C 1 2

7. EXERCISES Nitrogen nuclide has 3 isotope : 7 N 12 ; 7 N 14 ; 7 N 16 Why 7 N 12 ; 7 N 14 ; 7 N 16 are called isotopes?? Explain ! Mention isobars for 7 N 16 ! Mention isoton for 7 N 12 !

8. Answer : Because their sum of proton are same but sum of neutron are different 7 N 16 isobars to 8 O 16 7 N 12 isotons to 4 Be 9
