Why is it said that the nucleus of an atom contains almost the entire mass and not the entire mass?
Yes. An electron, one of those little negatively charged critters that forms up around the nucleus of an atom, has little mass compared to the nucleons. (Nucleons are protons and neutrons - the particles that make up the nucleus). In fact, the mass of an electron is less than 1/1800th the mass of a proton. All the electrons in any given atom account for only a tiny amount of the total mass of that atom. Almost all the mass is accounted for the protons and neutrons (if any) in the nucleus. It's that simple, and you already show that you know it.
What else can I help you with?
Why is the entire mass of an atom is almost the nucleus?
almost the entire mass of an atom is in the nucleus A proton or a neutron approximately 1840 times heavier than an electron.So weight of electrons is negleteble.
Most of the atom's positive charge and almost all of its mass is located in this region of the atom?
The nucleus is the region of the atom where most of the atom's positive charge and almost all of its mass is concentrated. It contains protons and neutrons tightly packed together. The electrons orbit around the nucleus in different energy levels.
What is a nucleus in a atom?
the nucleus is the center of an atom that contains the positively charged protons and the neutrally charged neutrons. It contains most of the mass of the atom.
What part of the atom contains the majority of mass an atom has?
The nucleus contains the mass.
What is larger a carbon atom or nucleus?
The nucleus of a carbon atom is much smaller than the entire carbon atom itself. The nucleus contains protons and neutrons that account for the majority of the atom's mass, while electrons orbit around the nucleus in a relatively large atomic cloud.
What part of the atom contains most of its mass?
The nucleus, made up of protons and neutrons, contains most of an atom's mass.
Why is the entire mass of an atom is almost the nucleus?
almost the entire mass of an atom is in the nucleus A proton or a neutron approximately 1840 times heavier than an electron.So weight of electrons is negleteble.
Particles found in the nucleus of an atom?
The nucleus of an atom always contains at least 1 proton. It almost always contains at least 1 neutron as well.
Where is all the mass of an atom concentrated in?
The mass of an atom is concentrated in its nucleus, which is composed of protons and neutrons. The nucleus is extremely small compared to the overall size of the atom, but it contains almost all of the atom's mass. Electrons, which are much smaller in mass, orbit around the nucleus.
Most of the atom's positive charge and almost all of its mass is located in this region of the atom?
The nucleus is the region of the atom where most of the atom's positive charge and almost all of its mass is concentrated. It contains protons and neutrons tightly packed together. The electrons orbit around the nucleus in different energy levels.
What is the most dense part of an atom?
The nucleus is the most dense part of an atom.
An atom contains what?
An atom contains protons and neutrons in the nucleus (though Hydrogen does not have neutrons) and electrons orbiting the nucleus.
What is a nucleus in a atom?
the nucleus is the center of an atom that contains the positively charged protons and the neutrally charged neutrons. It contains most of the mass of the atom.
What is the dense center of the atom called?
the denser part of an atom is the nucleus. about 99% of the mass of an atom is concentrated within the atom.
What part of the atom contains the majority of mass an atom has?
The nucleus contains the mass.
What is the core of an atom called?
Atoms are made of a nucleus that is surrounded by electron clouds. The nucleus is formed from all the atom's protons and neutrons. Proton and neutrons are made up of even smaller particles called quarks.
The small central part of an atom?
The "dense" central portion of an atom is called the nucleus. The nucleus of an atom contains neutrons and protons.
