A
Same # Protons, different # neutrons
3
Q
Isotopes Uses
A
Biological/Medical tracing
4
Q
Ion Formation
A
Formed through ionic bond where atoms attempt to gain a full valence shell by giving up electrons or taking electrons. NO SHARING
5
Q
Anions
A
Ions that are negatively charged
6
Q
Cations
A
Positively charged ions
7
Q
Ions must…
A
have charge due to the way their bonds are formed and because they have an unequal ratio of electrons to protons
8
Q
Why are ionic bonds formed?
A
Opposites attract, attracted because of their different electronegativies
9
Q
Ionic Bond Exampe
A
Na and Cl ionic bond become sodium chloride
