Subatomic Particles, chemistry assignment help

) 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:

Ion	Number of electrons
Al3+
Fe3+
Mg2+
Sn2+
Co2+
Co3+
Li+
Cr3+
Rb+
Pt2+

3.)Enter the correct number of protons and electrons in the corresponding blanks:

Ion	Number of protons	Number of electrons
Co2+
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 Number	Element Symbol	Ion Charge
11
53
38
55
88
9
13
33
12
20

When asked to enter the charge of the ion, you must enter the number along with 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 up with two more protons than electrons, you must enter the value as 2+ (or +2; I have set up the assignment to accept either ).

5.)

Enter the correct number of protons, neutrons, and electrons for the given ion:

 Ion
Protons
Neutrons
ElectronsNi
²⁺-59  Zr
⁴⁺-91  Se
^2--79  Mg
²⁺-24  Ag
⁺-108  Po
⁴⁺-209  Ta
⁵⁺-181  Ga
³⁺-70  Zn
²⁺-66  Os
⁸⁺-190
