How many neutrons are in potassium-50?

Chemistry
2 answers:
madam [21]3 years ago
8 0

Answer:

31 neutrons

Explanation:

Potassium has 19 protons (you can tell by the atomic number)

Potassium-50 is an isotope, meaning that there are a different amount of neutrons than normal.

Protons never change so subtract 50 from 19 to get the number of neutrons.

1) Why are the antimony and beryllium ions so small? Differentiate between the causes.
Viefleur [7K]
1. For this question, the adjective small must be percepted in a relative sense. This is because it is not the smallest ion (that would be hydrogen). It could be that the antimony and beryllium ions are smaller compared to their neutral forms. This is because they donate electrons when ionized. As a result, the electrons are reduced, so does the electron cloud which makes the radius much smaller.

2. The periodic table is arranged in terms of increasing atomic number. For neutral atoms, the number of protons (atomic number) is equal to the number of electrons. So, the farther we go down the table, the higher the atomic number. The higher the atomic number, the bigger the electron cloud which makes the atomic radius bigger. Because by definition, atomic radius is the length from the nucleus to the farthest electron from the nucleus.
