1)
2)
a) Neutral
b) The same
c) Protons = 9, neutrons = 10, electrons = 9
3)
a) A charged particle/ atom/ molecule
b) Positive ion
c) Negative ion
4) Isotopes are different versions of the same element; isotopes have the same number of protons and a different number of neutrons (or, you could say that isotopes have the same atomic number and a different mass number/ relative atomic mass)
5)
a) Chlorine-35: Protons = 17, neutrons = 18, electrons = 17
Chlorine-37: Protons = 17, neutrons = 20, electrons = 17
b) They both have 17 protons
c) They have a different number of neutrons – chlorine-35 has 18 neutrons and chlorine-37 has 20 neutrons
