Annette [7]3 years ago

 <span>A solution is somthing desolved in somthing else. By desolved i mean it needs to have some particals ionized a solid you place in water that dissosiates (ions split apart from each other) makes a solution a good solution you can make in your kitchen is a salt-water solution, Put some regular table salt in a glass and stir it and you will notice the salt "disapears" what happens is the sodium ions and the chloride Ions seperate and 'hide' between water molocules. 

In basic terms only some substances can make a solutions others are refered to as insoluble as they can't be seperated in water or another solvent. In actuality however all ionic compounds (compounds that are composed of ions) are at least somewhat soluble, but don't dissociate well at all in some solvents. 

Hope that helps</span>

A particular isotope of uranium has a nucleus with 92 protons and 143 neutrons identify this isotope in two diffrent ways
inn [45]

Isotopes can represented in two ways. In the first way, the element's symbol is used with mass number at the upper left and atomic number written on the lower left of the symbol. In the other form of representation, the isotope name is written with a dash and mass number.

Given that the isotope has 92 protons. So the atomic number is 92.

The isotope has 143 neutrons

So the mass number = Total number of protons + Neutrons

                                  = 92 + 143 = 235

Therefore, the two ways of representing the isotope is:

1. ^{235}_{92} U

2. Uranium-235
