Question

Use the following table to answer the question: Element Mass Number Atomic Number Aluminum 27 13 Nitrogen 14 7 Helium 4 2 Fluorine 19 9 Which element has the most neutrons in the nucleus? Aluminum Nitrogen Helium Fluorine

Answer 1

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

Answer 2

Answer:

aluminum has the most atomic number

Explanation:

the atomic number is equal to the protons and neutrons

the protons in aluminum in this case is 13, so the neutrons are 14.
