Question

38.) Naturally occurring copper is a mixture of two isotopes. One of these has 29 protons and 34 neutrons, the other one two more neutrons. Complete the table for both isotopes:
Protons # Neutrons # Electrons Atomic # Mass#
Isotope 1 29 34
Isotope 2

Answer 1

atomic number = number of protons
mass number = number of protons + neutrons
in a neutral element = number of protons = number of electrons
hope this helped!

Answer 2

ok so for isotope1 its 29 protons 34 neutrons 29 electrons 29 atomic number and 63 mass
istotope2 29protons 36 neutrons 29 electrons 29 atomic number and 65 mass

Answer 3

you got it :)

Answer 4

ok thanks!
