Question

Which of the following is true about the element below J. There are 29 Neutrons K.The atomic number is 64 L. There are 29 electrons M. There are 64 protons

Answer 1

Odd couple. Surprisingly, the team found evidence for isotopes of aluminium (which has 13 protons) with both 29 and 30 neutrons.copper

For April, we have selected copper, a transition metal with chemical symbol Cu and atomic number 29.
