4) their metallic properties increase and their atomic radii increase.
Global Warming. The temperature is rising ever so slightly , but the effect is astronomical.
Holonium and Gadolinium has the highest number of neutrons in the nucleus.
Looking at the atoms listed;
Dysprosium has 66 protons
Holonium has 67 protons
Neodymium has 60 protons
Europium has 63 protons
Gadolinium has 64 protons
Then,
Number of neutrons = Mass number - number of protons
For Dysprosium
157 - 66 = 91 neutrons
For Holonium
162 - 67 = 95 neutrons
For Neodymium
149 - 60 = 89 neutrons
For Europium
148 - 63 = 85 neutrons
For Gadolinium
159 - 64 = 95 neutrons
Hence, Holonium and Gadolinium has the highest number of neutrons in the nucleus.

The zone and its characteristics include the following:
- Subpolar low: Lies along the polar jetstream.
- Horse latitudes: The trade winds and westerlies originate here.
- Doldrums: Heavy precipitation, little wind.
<h3>What is Horse latitude zone?</h3>
This is referred to regions which is located at about 30 degrees north and south of the equator and forms the basis of westerlies.
The other zones such as doldrums are also found at the equator with their respective features and can be seen above. This therefore makes it the most appropriate choice.
