APEMAN

How to figure out the number of protons, neutrons and electrons for any element using the periodic table.

APEMAN stands for

A= Atomic number
P= Protons
E= Electrons
M= Mass number
-Atomic number=
Neutrons

Multiple Choice

What does the A in APEMAN stand for?

Atomic number

atom

Multiple Choice

What does the P in APEMAN stand for?

positive

proton

Multiple Choice

What does the E in APEMAN stand for?

electrons

electricity

Multiple Choice

What number represents the protons for aluminum?

26.982

Multiple Choice

What number represents the electrons for aluminum?

26.982

APEMAN stands for

A= Atomic number
P= Protons
E= Electrons
M= Mass number
-Atomic number=
Neutrons

So, protons and electrons are the same as the atomic number.

Neutrons are trickier... you have to do a little fancy subtraction

M stands for Mass number
to find the mass number, take the atomic number and round it to the nearest whole number.

Multiple Choice

What is the atomic mass of aluminum?

26.982

Multiple Choice

What is the mass number for aluminum?

26.982

So if the mass number for aluminum is 27, how do we find the neutrons?

Mass number- Atomic number = Neutrons
(M-A=N)
So... 27-13= 14 neutrons!

What is the number of electrons in calcium?

40.078

Multiple Choice

Get it? That's APEMAN!

Try another one.

What is the number of neutrons in calcium?

40-20=20

40.078- 20= 19.922

A couple of tips

There are ways to check if your answer makes sense:
Your answers will always be whole numbers
protons and electrons will always be the same number
neutrons for the first 20 elements will be close to or the same as the atomic number
