How many electrons are supposed to be there when the atomic mass unit is 6?

(neutron is 3 and proton is 3 as also, im getting confused on how many electrons im supposed to put in my project please understand! T^T)

QUESTION

How many electrons are supposed to be there when the atomic mass unit is 6? neutron is 3 and proton is 3.

ANSWER: 3 electrons

Explanation:

If you are looking for the missing value of certain sub-atomic particles, here’s a simple mnemonic to help you figure out the answer.

Remember the term “APE MAN” in which it stands for:

  • A - Atomic number
  • P - Protons
  • E - Electron

These three variables are equal or have the same value.

   M - Ma.ss number (mass unit)

— A - Atomic number

—————————————-

   N - Neutron

Meaning, if you subtract the given value of the atomic number from the mass number, you’ll get the total number of neutrons present in the element.

Now, let’s try to solve your problem.  

Following the “APE MAN,” we get,

  • A - Atomic number = unknown
  • P - Protons = 3
  • E - Electron = unknown

Since we know the value of protons, we can safely assume that the atomic number and the electrons are also 3.  

And now, since you already know the value of those sub-atomic particles, you can easily determine the rest of the missing values.

    M - 6

—  A - 3

—————————————-

    N - 3

Therefore, an element with a mass unit of 6 has:

  • Atomic number = 3
  • Protons = 3
  • Electrons = 3
  • Ma.ss unit = 6
  • Neutrons = 3

Note: This is not the standard way of solving problems regarding the missing values of the sub-atomic particles in an element. I used this technique before, and it helped me figure out those missing values. For me, it makes my life easier. But still, the most precise method is using your periodic table as a reference.

I hope this helps!
