SpletThe easiest way to approach this problem is to set up a system of two algebraic equations, where H and D are the percentages of H (mass = 1amu) and D (mass = 2amu), respectively. Your set up should look like the following: H + D = 1 percent (percent H + percent D = 100%) 1H + 2D = 1.008 (atomic weight calculation) SpletThe mass number is equal to the sum of the number of protons, neutrons, and electrons the sum of the number of the electrons and protons. the sum of the number of protons and …
Splet22. mar. 2024 · The mass number (represented by the letter A) is defined as the total number of protons and neutrons in an atom. Consider the table below, which shows data from the first six elements of the periodic table. Consider the element helium. Its atomic number is 2, so it has two protons in its nucleus. Its nucleus also contains two neutrons. Splet1st step. All steps. Final answer. Step 1/2. Let's use algebra to solve the problem.
