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.

Answer:
are gases at room temperature
usually do not react with other elements
are in a group called the noble gases
are nonmetals
Explanation:
The elements in group 18 or group O are the inert elements. They have completely outermost shell and are not reactive. Every atom reacts with another in order to be like the noble gases.
- All of the elements here are gaseous.
- They do not readily react with other elements.
- They are called noble gases, inert gases, or group O elements.
It should be noted that group 17 elements are very reactive compared to the group O elements.
It weathers it down until it is nothing but sediment in a river , lake or ocean
Answer:
No, they dont have enough and they'd need 1 more quart of milk
Explanation:
lets see, 2 pints in a quart, if they have 6 quarts so 12 pints, they'd need 1 more quart to make 14 milkshakes
for 20, 6 12 oz bottles is 72 oz, 1/2 a gallon is only 64 so the 6 bottles is 8 more oz of water, Hoshi boght more
