Carbon c-12
2
Q
Isotopes
A
Are atoms that have same # of protons and electrons but not neutrons
3
Q
T or F : isotopes have same mass
A
False, isotopes all have diff mass and the atomic mass is its average
4
Q
How might isotopes of same element differ and be similar?
A
Chemical = similar as the protons and electrons are same and they are inchage of charactersties Physical = might differ
5
Q
Difference between isotope and radioisotopes
