If the atomic number of an element is six and the atomic mass is 15, how many neutrons does it have?
*
1 point
6 Neutrons
9 Neutrons
15 Neutrons
To find the number of neutrons, subtract the atomic number from the atomic mass. In this case, the atomic number is 6 and the atomic mass is 15. Therefore, the number of neutrons is 15 - 6 = 9 neutrons.
To find the number of neutrons in an atom, you subtract the atomic number from the atomic mass. In this case, the atomic number is 6 and the atomic mass is 15.
Number of neutrons = Atomic mass - Atomic number
Number of neutrons = 15 - 6
Number of neutrons = 9
Therefore, the element with an atomic number of six and an atomic mass of 15 has 9 neutrons.
To determine the number of neutrons in an atom, you need to subtract the atomic number from the atomic mass. In this case:
Atomic number = 6
Atomic mass = 15
Neutrons = Atomic mass - Atomic number
Neutrons = 15 - 6 = 9
Therefore, the element with an atomic number of six and an atomic mass of 15 has 9 neutrons. So the correct answer is "9 Neutrons".
