Alpha and Beta Decay

A neutron changes into a proton and an electron releasing this type of particle.

This particle can be stopped by a piece of paper.

This particle has 2 protons and 2 neutrons like a helium nucleus.

This particles can travel only a few centimeters through the air.

What is a beta particle?

Is the following alpha or beta decay?

²⁴³U → ____ + ²³⁹Th

During alpha decay the mass changes by (a)   , while the proton number changes by ​ (b)   . During beta decay the mass changes by ​ (c)   , while the proton number changes by​ (d)   .

If an atom of Americium-231 (Am) goes through alpha decay, what would you have at the end?

What is emitted during the alpha decay of Radium-222 (Ra-222)?

In alpha decay when the top number decreases by 4, what are you actually losing?
