How many protons are in an isotope of sodium with a mass number of 25? What is the average atomic mass of sodium? What is the atomic number for livermorium? What is the atomic number of americium? What is the atomic number of curium? What is the atomic number for argon? What is the...
What is the most common isotope of argon? Isotopes Explained: Elements are classified by the number of protons in the nucleus of the atom. However, there is no set rule for how many neutrons can be in the atom's nucleus. Because this number can vary, we classify the different, naturally...
Why is neon an unreactive monatomic gas? Who discovered tellurium? Why is helium inert? Write the complete electron configuration for the argon atom. Is Argon classified as a metal or as a non-metal? How is calcium manufactured? What are noble gases used for?
Answer and Explanation:1 The average atomic mass of oxygen is 15.999 AMU. This value rounds to 16, which indicates that oxygen-16 is the most abundant isotope of oxygen... Learn more about this topic: Average Atomic Mass | Definition, Formula & Calculation from...
