Answer:
13
Explanation:
The mass number of an atom is the sum of the number of protons and neutrons.
27 = protons + 14
protons = 13
The number of protons is equal to the atomic number.
Answer: 41 or Niobium
Explanation: To get the number of Protons or Electrons given the number of Neutrons and Mass, you have to add the given numbers. This gives the number of Protons and Electrons which is the same number as the Atomic number. So, 14 Neutrons plus the mass of 27 is equal to 41, which gives the element Niobium
