[The nucleus has more massive parts (protons and neutrons) than the surrounding electron cloud].
This is because 99.9999 % of the volume of space that the Atom occupies is Empty Space.
Below is another person's answer... longer and more complicated than mine. it was said to have a repeated answer.
The nucleus accounts for 99.9% of an atom's mass simply because neutrons and protons are much more massive than electrons.
Mass of proton: 6726 x 10^(-27) kg
Mass of neutron: 1,6749 x 10^(-27) kg
Mass of electron: 0,00091x10^(-27) kg
Even though the electron cloud accounts for most of the atom's area, a huge percentage of the cloud is empty space, and the electrons within it are minuscule to begin with. The highly dense nucleus contains most of the mass.
What else can I help you with?
What information does the percent composition in an atom in a molecule give?
The relative amount of mass an atom contributes to a molecule
What infrmation does the percent composition of an atom in a molecule give?
The percent composition of an atom in a molecule indicates the relative mass contribution of that specific atom type to the total molecular mass. It is calculated by dividing the mass of the atom in one mole of the compound by the molar mass of the entire compound, then multiplying by 100. This information is useful for understanding the molecular structure, stoichiometry, and potential reactivity of the compound. It also aids in determining empirical formulas and analyzing elemental compositions in chemical reactions.
The relative atomic mass of an atom can be found by comparing the mass of the atom to the mass of?
The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
What represents most of an atom's mass?
The nucleus of an atom represents most of an atom's mass.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
Where can the most mass be found in an atom?
Essentially all of the atom's mass is in the nucleus. In the lightest atom, that of hydrogen, it's about 99.95 percent. In the heaviest naturally occurring atom, that of Uranium238, it's about 99.979 percent.
What is 15 percent off 999 dollars?
15 percent off 999 dollars: $999 x 0.15 = $149.85

Aproximately 99.9 percent of the mass of an atom is in the?
the nucleus (protons and neutrons)
Is .999 percent the same as 99.9 percent?
.999 as a decimal is the same as 99.9%, However .999% is not the same as 99.9% where both are percentages.
What is 10 percent off of 999?
899.110% off of 999= 10% discount applied to 999= 999 - (10% * 999)= 999 - (0.10 * 999)= 999 - 99.9= 899.1
What is the percent of 9.99?
999%9.99= 9.99 * 100%= 999%
What information does the percent composition of an atom in a molecule give?

What is the percent by mass in sulfur in sulfur oxide?
The percent by mass of sulfur in a sulfur oxide compound can vary depending on the specific compound. For example, in sulfur dioxide (SO2), which contains one sulfur atom and two oxygen atoms, the percent by mass of sulfur would be approximately 50%. In sulfur trioxide (SO3), which contains one sulfur atom and three oxygen atoms, the percent by mass of sulfur would be approximately 40%.
Over 99 percent of the mass of an atom is contained where?
Over 99% of the mass of an atom is contained in the nucleus, where protons and neutrons are located. Electrons, which have negligible mass compared to protons and neutrons, occupy the remaining space in the electron cloud surrounding the nucleus.
