how many protons, neutrons and electrons are contained in each element? a)27 over 13 AI, b)35 over 17 CI, c)34S

Since the number on top is the mass number (number of neutrons and protons) while the number at the bottom is the atomic number ( number of protons)

A) 13 protons, 14 neutrons (27-13)

For the number of electrons it has to be equal to the number of protons if the atom is uncharged.

Therefore you have 13 electrons.

B) 17 protons, 18 neutrons (35-17)

18 electrons

C) What is the atomic number of Sulphur - need slightly more info

Theoretical temperature at which molecules stop moving and no more heat can be removed from the object. kelvin: absolute zero degrees. none of the above.

Answer//the law of conservation of mass.;
