Answer:
A. Electric currents produce magnetic fields.
Explanation:
Hans Christian Ørsted discovered that electric currents had a property of producing magnetic fields. This finding was the first established relationship found between electricity and magnetism.
He noticed that a compass deflected when current was switched on and off and this marked the first established relationship between electricity and magnetism.
Answer is the mass of the atom. Protons + neutrons= mass
Let's say you have oxygen with a mass of 16.
Oxygen has 8 protons
To find neutrons subtract 16-8= 8
So it would also be 8 neutrons.
Example of how to find mass if you know protons + neutrons:
Sodium has 11 protons and 12 neutrons. Add the protons and neutrons
11 + 12= 23
Mass is 23
I am going to say it is false.
It shows the atomic number
