Answer:
5.10¹¹ N/C
Explanation:
As we have a proton and a neutron, we can consider that they both have the same charge, this is:
e- = e+ = |1,6x10⁻¹⁹ C| , this number is in absolute value
Then, the formula needed to calculate the magnitude of the electric field from a charged particle is:
E= kqQ/r²
Where:
K= Coulomb constant
Q= charge
r = distance between two charges
Then:
E= 8.99x10⁹N/C²*(1.6x10⁻¹⁹C)/(5.3x10⁻¹¹m)²
E=5.12x1011 N/C
It is important that this value is a magnitude, it does not have any sign (positive or negative), for the magnetic field
b.) mixtures are made up of more than on component. A pure substance is like a diatomic element, like O2, while a mixture is more like a salad, and can be separated by physical means.

Here's what I find.
Explanation:
Many scientists contributed to our model of the atom.
Among those who received the Nobel Prize for their work are:
1906 — J.J. Thomson — discovery of the electron
1908 — Ernest Rutherford — nuclear model of the atom
1922 — Niels Bohr — planetary model of the atom
1922 — Albert Einstein — quantum mechanical model of the atom
1935 — James Chadwick — discovery of the neutron
