Answer:
B
Explanation:
when elements reacts to form a compound the elements properties changes completely. This happens due to the fact that a chemical reaction has taken place. In a chemical change new substances are formed and the properties of the products differ entirely from that of the reactant.
for example if hydrogen combines with oxygen to form water, the property of hydrogen differs from oxygen and also both differs chemically when compared to water.
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.
