21. Why are radioactive nuclei unstable?
a. There is not the proper neutron to proton ratio resulting in a stable nucleus
b. There is too much energy stored in the bonds between atoms
C. They need to gain/lose electrons to have a full valence energy level
d. Protons reverse their charges and begin to repel one another

Answers

Answer:

a. There is not the proper neutron to proton ratio resulting in a stable nucleus

Explanation:

Radioactive nuclei are unstable because they do not have a proper neutron to proton ration that can result in a stable nucleus for them.

Every atomic nucleus has specific neutron to proton ratio. The ratio ensures the stability of the nucleus. Any nucleus with a neutron/proton combination different from its stability ratio will be unstable and split into one or more other nuclei. This is usually with an attendant emission of small particles of matter and electromagnetic ionizing radiation and energy.

Write the information obtained from solubility curves.​

Answers

Explanation:

The solubility curve helps us to compare the solubility of difference substances at same temperature. It gives the idea that solubility changes with the temperature. The solubility curve helps us to predict which substance will crystalize out first from hot solution containing two or more solutes.

which period of the periodic table is completely made up of elements with no known stable ions?

Answers

Answer:

I think the answer is period 7

Explanation:

The period in periodic table, in which no stable ions of elements exists is 7th period. They contains actinides.

What are actinides?

Actinides are 7th period elements classified to F block of periodic table. A periodic table contains vertical columns called groups and horizontal rows called periods.  Each elements are classified into suitable groups based on their similarity in properties with other group elements.

There are four blocks in periodic table which are s, p, d and f block. S block elements are metals and d block contains transition metals and p block have non metals including gases and metalloids.

Actinides are f- block metals. All the elements in the period are radioactive. That's why they don't have a stable isotope or ion. They continuously undergo radioactive decay by the emission of charged particles.

Hence, the period containing unstable elements is 7th one.
