Complete Question:

Which does not describe the relationship between nucleus and the electron cloud of an atom?

Group of answer choices.

A. the electrons move faster than the particles in the nucleus

B. the masses of the nucleus and electron cloud are balanced

C.the charges of the nucleus and electron cloud are balanced

D.the electron cloud takes up much more space than the nucleus

Answer:

B. the masses of the nucleus and electron cloud are balanced

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.

Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.

In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

An electronic cloud can be defined as a group of negatively charged electrons circulating around an atomic nucleus. It is typically referred to as valence electrons.

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others.

Both the protons and neutrons of an atom of a chemical element have a mass of 1 atomic mass unit (amu) while an electron have an approximate mass of 0 atomic mass unit (amu).

Hence, the masses of the nucleus and electron cloud of an atom cloud are not balanced.
