Where are the electrons in real action to the nucleus
Around the nucleus on shells
Why are the overall charge of an atom neutral
Bec they have an equal number of protons and electrons
Why do ions have an overall charge
Becuase there isn’t an equal number of electrons to protons
What does the atomic number tell you
The number of protons
What does the mass number tell you
The number of protons and neutrons in an atom
Is the mass number or atomic number bigger
The mass number is bigger than
How to calculate the number of neutrons using the numbers on a periodic table
Takeaway the atomic number from the mass number
What are isotopes
Atoms with the same number of protons but different number of neutrons
