An element can be represented as:
You can determine the identity of the element using its atomic number:
Atomic number (Z):
• represents the identity of the element
• reveals the number of protons
• in a neutral element:
# of protons = # of electrons
Mass number (A)
• reveals the number of protons and neutrons
mass number = # of protons + # of neutrons
carbon atomic number = 6
What are the atomic number, mass number, and symbol for the carbon isotope with 7 neutrons?
