We’re being asked to identify the element, number of protons and number of neutrons in 3374X.
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
Identify the element represented by each of the following symbols and give the number of protons and neutrons in each.
Identify the element 3374 X.
