They don't..?

Penetration: Gamma > Beta > Alpha

1. they get stopped by paper

2. they are larger than beta particles

3. they have more electrons then beta

iGCSE requires you to know

i'll hand it out:

-Alpha has more mass, therefore it is more likely to ionize with the colliding material
-Alpha has a stronger charge, attract and other crap
-Ionizing caused by large mass's usage of energy when moving

alpha particles have only 2 neutrons and 2 protons

they only get electrons once they ionize with a material

you're thinking of beta

compared to others, where beta has a near-non existent mass (electrons), yet a negative charge (weaker than alpha), gamma has no mass or charge

Let me go at it

Beta has less and travels more and ionises less due to its smaller size and lack of collision whereas alpha collides more thus ionises more causing less travel.
Out of the Two Alpha is more dangerous if present in edible or drinkable items.

The when the atoms are split more [neutrons] are fired off which hit more particles, reacting more

charges of radioactive nuclei:

alpha - 2+ (2 protons)
beta - 1- (or 1+ if positron - 1 nuclei)
gamma - 0

therefore, alpha has the strongest charge and is more likely to electrostatically attract to the conventional neutral surface in comparison to gamma and beta
