Because more than 99 % from the mass of an atom is concentrated in the nucleus (protons + neutrons).

Which is more massive an atoms nucleus or an atoms electron cloud?

The nucleus, consisting of protons and neutrons, is much more massive than the electrons.


Where is the massive part located in an atom?

in the center. Its called a Nucleus. It controlls the atom


Is the electron cloud the most massive part of the atom?

No, it is not. Almost all of the mass of an atom is located in the nucleus. The proton, that carrier of the positive electrical charge, is some 1836 times more massive that the negatively charged electron that it attracts to "build" an atom. If we take a look, we'll find that in a simple hydrogen-1 atom, a single proton is in the nucleus and a lone electron makes up the electron cloud. And the nucleus is about 1836 times more massive than the "rest" of the atom. In a helium-4 atom, two protons and two neutrons form the nucleus and a pair of electrons form the electron cloud. In this case, the nucleus is about 7,444 times as massive as the electrons. As we move up the periodic table, the figure gets even more lopsided.


What does the nucleus make for the cell?

The nucleus produces ribosomes that are then used to make proteins within the cell. Additionally, the nucleus houses and protects the cell's genetic material in the form of DNA, which contains instructions for the cell's functions and characteristics.


The nucleus makes up 99 percent of the atoms what?

The nucleus makes up nearly all of the mass of an atom, with over 99% of its mass concentrated in the nucleus. Within the nucleus, most of the mass is found in the protons and neutrons, while the electrons surrounding the nucleus contribute very little to the overall mass.

Most massive particles in an atom?

99.9% of an atom's mass is concentrated in the nucleus, with protons and neutrons having almost the same mass, with neutrons being slightly higher. So your question would be, 'What atom has the most protons and neutrons combined?' And that answer is Nobelium. Nobelium has 102 protons and 160 neutrons which makes it the most 'massive' atomic particle, even more so then Lawrencium which has 103 protons but only 159 neutrons. Of course, in a few months, we could have a new, more massive element.


How does the mass of the nucleus compare to the mass of the electron?

The nucleus is far more massive than the electron cloud. The mass of the electron cloud is almost negligible compared to that of the nucleus.

What makes an element more massive?

The number of protons and neutrons in the nucleus of an atom determines its mass. Elements with more protons and neutrons are more massive. Additionally, the mass of an element can be influenced by the presence of isotopes, which have varying numbers of neutrons.


What does nucleus make?

To put it simply, the nucleus makes ribosomes.


Where is most the mass of an atom called?

The majority of an atom's mass is found in its nucleus, which is located at the center of the atom. The nucleus is composed of protons and neutrons, which are much more massive than the electrons that orbit the nucleus.

the nucleus is made of Neutrons which are neutral and potrons which is positive .
