Question

Can someone help me on a worksheet for chemistry, i will fan and give you a medal if you help me i really need the help :)

Answer 1

Introduction
There are over 100 different types of atoms. Some of these atoms are very unstable.
Over time, the nucleus of an unstable atom will lose energy by emitting various
particles spontaneously. This process is called nuclear decay. There are different
types of nuclear decay, including alpha and beta decay. There are two different types
of beta decay: beta minus (β–
) decay and beta plus (β+
) decay. Some scientists refer
to beta minus decay simply as beta decay, for convenience. This activity only deals
with this type of beta decay.
In this activity, you will determine the differences in the charge and mass of alpha
and beta minus (β–
) particles and how their emission affects atoms.

Answer 2

1. Alpha Particles
a. What is the mass number of an alpha particle?
