Step 2:Find the number of protons of the element from the periodic table. The number of protons is equal to the atomic number of the element. Step 3:Add the number of protons found inStep 2and the number of neutrons given in the problem. This sum is the mass number of the element. ...
To understand how the mass number and atomic number change during alpha decay, let's break down the process step by step.Step 1: Understanding Alpha Decay Alpha decay is a type of radioactive decay in which an unstable nucleus
Steps to Find Ionization Energy Step 1:Determine the effective nuclear charge for each element. Step 2:Rank elements by size. Elements get larger moving down the periodic table, and elements with a larger effective nuclear charge will be smaller. ...
How to calculate atomic mass is an exercise that's vital to know in the fields of chemistry or physics. There is more than one way to find atomic mass, too. Which method you use depends on the information you're given. First, it's a good idea to understand what exactly, atomic mass...
