Dante drew a diagram to show how a wire uses the magnetic field of a magnet to induce an electric current. How can Dante correct
the diagram?
He can move the wire upward instead of downward.
He can connect the wire to both ends of the ammeter.
He can change the wire from coiled to straight.
He can place the wire between the poles of the magnet and not move it.

Hope it cleared your doubt.
In a neutral atom, the number of protons is equal to the number of electrons.
Given that the charge on the ion of the element is -1. This means that there is one electron more than the number of protons in the element.
The atomic number = Number of protons = 57 -1 = 56
Element with atomic number 56 is Barium.
Mass number of the element = Number of protons + Number of neutrons
= 56 + 80 = 136
So the identity of the species:
