Use the following table to answer the question: Element Mass Number Atomic Number Aluminum 27 13 Nitrogen 14 7 Helium 4 2 Fluori ne 19 9 Which element has the most neutrons in the nucleus? Aluminum Nitrogen Helium Fluorine
1 answer:
Answer:
Aluminium have the most neutrons in the nucleus.
Explanation:
The number of neutrons in the nucleus can be calculated by subtraction of the atomic number from the mass number.
neutrons in aluminium nucleus = 27 - 13 = 14
neutrons in nitrogen nucleus = 14 - 7 = 7
neutrons in helium nucleus = 4 - 2 = 2
neutrons in fluorine nucleus = 19 - 9 = 10
