Explain how you can determine the number of neutrons in the nucleus of an atom of any of the elements listed in the table.

daser333 [38]

Different explanations that lead to the same result

-You need to substract the number of protons from the mass number.

-Mass number - atomic number= number of protons

-Following this equation:

CARBON

atomic number= 6

mass number= 12

mass number= protons + neutrons

12= 6 + x

x= 12-6

x= 6

Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where need

gregori [183]

Answer:

Explanation:

Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created. Include all free radicals by right-clicking on an atom on the canvas and then using the Atom properties to select the monovalent radical.
