Problem

Answer the following questions. 

Flerovium was made by bombarding plutonium-244 atoms with calcium-48 ions, effectively combining the two different nuclei to give a flerovium nucleus.

Give the number of protons and neutrons in a plutonium-244 nucleus: ______ protons ______ neutrons

Give the number of protons and neutrons in a calcium-48 nucleus: ______ protons ______ neutrons

Combining these nuclei, how many protons and neutrons would be contained in the new flerovium nucleus:______ protons ______ neutrons

The isotope of flerovium initially formed by the above process is very unstable, and it quickly loses three neutrons. Would the resulting atom correspond to a different element (circle one)?  Explain. Yes or No

 

Would you expect the compound FlO2 to be ionic or molecular? __________________________

How should this compound be named? ______________________________________________

Flerovium was prepared using calcium ions. Assuming that these ions are the common ion formed by calcium, give the charge (magnitude and sign) and the number of electrons contained in one calcium ion.

 

charge of the ion _______   _____ total number of electrons in one calcium ion _______

        number    sign
