If you had a sample containing 55 alpha particles, how many protons would be present in that sample?
To determine the number of protons present in a sample containing alpha particles, you need to understand the structure of an alpha particle and identify the number of protons it contains.
An alpha particle is a particle that consists of two protons and two neutrons, which means it has a total atomic mass of 4. Since protons have a relative atomic mass of 1, an alpha particle will have a total of 2 protons.
Given that your sample contains 55 alpha particles, you can calculate the total number of protons in the sample by multiplying the number of alpha particles by the number of protons in each particle:
Number of protons = Number of alpha particles × Number of protons per alpha particle
Number of protons = 55 alpha particles × 2 protons per alpha particle
Number of protons = 110 protons
Therefore, there would be 110 protons present in the sample containing 55 alpha particles.
