12 neutrons

• The atomic number of the element is 11. Hence it contains 11 protons and 11 electrons since the element is neutral. Its mass number is 23 and hence it contains (23-11) = 12 neutrons.

Answer 2

Answer:

The atomic number of the element is 11. Hence it contains 11 protons and 11 electrons since the element is neutral. Its mass number is 23 and hence it contains (23-11) = 12 neutrons

Answer 3

Answer:

The atomic number of the element is 11. Hence it contains 11 protons and 11 electrons since the element is neutral. Its mass number is 23 and hence it contains (23-11) = 12 neutrons

Answer 4

Answer:

The atomic number of the element is 11. Hence it contains 11 protons and 11 electrons since the element is neutral. Its mass number is 23 and hence it contains (23-11) = 12 neutrons
