Question

An atom has atomic mass number 23 and atomic number 11 .Find the electron

Answer 1

Hi.....

here is your Answer:

✈Atomic number = Number of electron present in atom = Number of proton present in an atom

So,

✔electrons = 11
✔protons =11

:)

Answer 2

Given,

• The mass number of an atom = 23
• The atomic number of an atom = 11

To find,

• The number of electrons.

Solution,

We can simply find the number of electrons if an atom has atomic mass number 23 and atomic number 11.

    As we know,

Atomic number = number of protons = number of electrons in an atom

We are required to find the number of electrons in an atom.

Since the atomic number of an atom is 11, then the number of electrons is also 11.

The atomic number of an atom = number of electrons

                                              11  = number of electrons

Hence, if an atom has atomic mass number 23 and atomic number 11, then the number of electrons is 11.
