I want to thank your team (Jeff) for finding a new writer when you were unable to reach my existing writer to revise my paper. I appreciate your professionalism and efforts. Thanks
) Fill in the blanks with the appropriate charge corresponding to the given situation:
You must include the charge for the answer to be correct! Enter the number first, followed by the charge.
Lost five electrons:Gained two electrons:Lost three electrons:Gained four electrons:
2.) Enter the correct number of electrons in the corresponding blanks:
IonNumber of electronsAl3+Fe3+Mg2+Sn2+Co2+Co3+Li+Cr3+Rb+Pt2+
3.)Enter the correct number of protons and electrons in the corresponding blanks:
IonNumber of protonsNumber of electronsCo2+ Co3+ Cl- K+ S2- Sr2+ Al3+ P3- H+ Ce3+
4.)
For each of the following Atomic Numbers, enter the correct corresponding element symbol and charge:
Capitalization counts! The element symbol is case sensitive.
You must include the + or – sign for your charge to be counted correct.
Atomic NumberElement SymbolIon Charge11 53 38 55 88 9 13 33 12 20
Whenasked to enter the charge of the ion, you must enter the number alongwith the + or – for your answer to counted correct. Just entering a +or – with no number implies a charge of 1+ or 1-. So, if you end upwith two more protons than electrons, you must enter the value as 2+ (or+2; I have set up the assignment to accept either ).
5.)
