Element Block and APEMAN Strategy

Element Block and APEMAN Strategy

Element Block

• 1 - represents Atomic number which = Protons = Electrons

• H - represent the symbol

• 1.008 - represents Atomic mass which = protons + neutrons

• Hydrogen - represent element name

APEMAN Strategy

• In order to determine the number of protons and electrons in an atom, remember three things are always equal in a NEUTRAL atom

• Atomic # = Protons = Electrons

• When trying to find the number of neutrons in an atom, you will use the following:

• Mass # - Atomic # = Neutrons

APE

• Atomic number = Protons = Electrons (APE)

• A = 1

• P = 1

• E = 1

MAN

• Mass number - Atomic number = Neutrons (MAN)

• M = 1

• A = 1

• N = 0
