If I know the number of protons an element has do I know what element it is ?

Yes.

Explanation:

The atomic number is derived from the number of protons. For example: Radium has 88 protons and its atomic number is 88. Helium has 2 protons its atomic number is 2. Sodium's atomic number is 11 it has 11 protons.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
