Is it just   1/(7gt2)  or  1/(7gt2) Either way you must "rescue"  t  or t2 out of the ground, the denominator.  This means to multiply t or t2 by both sides of the equation.   Remember t or t2 must be alone.  So get rid of s...

The increase in atomic number causesf an increase in the strong positive charge of the nucleus.  Thus, the positive charge increases due to the number of positive protons increasing in the nucleus. The strong positive charge of the nucleus has a strong pull on the negatively charged electron...

These simple chemical formulas will help you with the formation of single, double and triple bonds.  The letter "n" = the number of carbon. Single:  CnH(2n + 2)......................has the most hydrogen.......very saturated Double: CnH(2n).....................

Yes the question might need to be rephrased.  You have to be familiar with Rutherford's and Bohr's model. Rutherford discovered, based on the gold foil experiment, that the atom consists of a dense positive nucleus with negative electrons traveling around it.  His model was known as...

I have a very interactive site that I used with my honors class.  It will help you build each atom's configuration consecutively.   http://intro.chem.okstate.edu/WorkshopFolder/Electronconfnew.html Remember, the periodic table is divided into 4 sections to represent sublevels (s,p,d,f),...

1) Set each monomial equal to 0          p - 5 = 0          p + 3 = 0 2) Solve.............         p - 5 = 0 ;   p = 5          p + 3 = 0 ;   p = -3
