Atomic number: 6 / the atomic number will always be the amount of electrons an element has 
Element: Carbon (C) 
Mass: 13 / you can find the mass by adding the protons and neutrons together 
Charge: 0 or neutral / if an element has the same number of protons and electrons it will be a neutral charge 
Isotope: Carbon-13 / all you do is take the element name and the mass and write the isotope like I did above 
I hope this help! If you have any questions feel free to ask
