Chemistry - Periodic Table+IE(check+help)
The following data lists the ionization energies for a given atom: IE1 = 738Kj/mol; IE2 = 1451Kj/mol; IE3 = 7733Kj/mol. Predict the valence electron configuration for this atom, and explain your reasoning. i do not understand this question but i will give it a try, please chec...

Chemistry - Periodic Table+Cations(check+help)
On which side of the periodic table would you find an element whose atom is likely to form a cation? Which atom property is related to this question? Ans: is it the right side of the periodic table that you would find the elements whose atom are likely to form a cation, since ...

Use Amending formula, rule of law and civil law individually in sentences. Please help me form sentences, i cannot crack my brain around these three.

density and density error (check calculations)
Calculate the density of earth and its density error d=m/v where m = 6.00*10^24kg and v = (4/3)(pi)(6359000)^3 = 1.07709...*10^21 m^3 therefore d=6.00*10^24/1.07709...*10^21 m^3 d = 5570.5254...kg/m^3 using the sig fig rule, in division and multiplication take the least decima...
