### What are First four steps of He fusion after Be?

The first four: 1. Be 2. C 3. O 4. Ne How I found this: Since Helium (He) has an atomic number of 2, add two to the atomic number of Be. Since the atomic number of Be is 4, and the atomic number of Helium is 2, you would add four plus two, which equals six. Carbon has an atomic number of six, so therefore it would be your next answer. The formula is the atomic number of Helium plus the atomic number of element you are provided with equals the atomic number of your answer. In simpler terms: atomic number of He+atomic number= atomic number of answer

### How do the mass number and the atomic number of an element different?

Atomic number equals the number of protons, the (atomic) mass number equals the sum of (the number of) protons and neutrons of the same element.The answer is: they're differing in the number of neutrons(Mathematically: Where A = p and M = p + n, the difference in A and M is n)
