Why: 39 (mass number of K) - 19 (atomic number or number of protons) = 20 (number of neutrons)

7 0

Answer:

20 approximately.

Explanation:

There are two variables that you could use to calculated: Atomic Number and Atomic Mass.

Atomic number refers to the number of protons that the atom has.

Atomic mass refers to the whole: protons and neutrons.

If we subtract:  Atomic mass - Atomic Number = Number of protons.

For potassium (K):

Atomic number: 19

Atomic mass: 39.09. (we round the number for the subtract).

So, 39 - 19 = 20.

<u>20 PROTONS.</u> Approximately.

1. The picture shows a (certainly) untrained electrician who appears to be confused or stuck over some problem that he does not know how to solve. The quotation means that untrained electrician can cause harm to themselves as well as people around them, which is much more dangerous than any electric shock that affects a single person.

2. The hazard in the situation is that the electrician does not know how to fix the problem and if he tries to fix it without having knowledge about it then something can go wrong and he or the people using the service that he has fixed can get an electric shock.

3. An untrained electrician is being exposed in the picture.

4. The character in the situation is vulnerable because he is untrained and he is working with electricity.
