Atomic Structure- Isotopes Flashcards
1
Q
What are isotopes?
A
Atoms with the same number of protons and electrons
But different numbers of neutrons
2
Q
How does isotopes affect mass and atomic numbers?
A
Isotopes of the same element have different mass numbers but the same atomic numbers
3
Q
Do isotopes react the same way in chemical reactions?
A
Isotopes have the same electronic configuration, so react in the same way in chemical reactions
4
Q

Cl 35
Cl 37
6
Q
How many neutrons do these have:
Cl 35
Cl 37
A
Cl 35 = 18
Cl 37 = 20
7
Q
Isotopes have different mass
As a result, what else will be different?
A
The m/z ratio
8
Q
What does m/z stand for?
A
Mass to charge ratio
9
Q
What does a different m/z mean will happen?
A
Isotopes will be detected separately
