Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explain…
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.

Chapter 4, Problem 94A
Interpretation Introduction

Interpretation:

A nucleus contains of 12 protons, the number of electron in the neutral atom needs to be determined.

Concept introduction:

The number of proton is the atomic number of the element. The protons and the number of the neutron are present in the nucleus of the atom.

Answer to Problem 94A

The number of electrons in the neutral atom is 12.

Explanation of Solution

The number of protons and the number of electron are equal in a neutral atom.

For any element -

Number of protons = Number of electron.Number of protons = Atomic number of the element.

The given number of protons is 12 so the number of electron is 12, and the atom is electrical neutral in nature.

Conclusion

The number of electron is 12 in neutral atom. The element contains the number of protons which in turn is equal to same number of electron.
