An atom has the same number of electrons (- ve charge) and protons (+ ve charge) to make the atom electrically neutral. An extremely powerful force, called the nuclear force, holds the protons together in the nucleus as they naturally repelled one another electrically.
The atoms of each chemical element have a different nucleus. An atom of hydrogen has one proton and no neutrons. An atom of nitrogen has 7 protons and 7 neutrons. Heavy elements have a large number of protons and neutrons. For example, the most common isotope of uranium, uranium-238 has 92 protons and 146 neutrons in its nucleus.
What else can I help you with?
True Or False most of an atom's volume is the space in which electrons move?
True, most of an atom's volume is the space in which electrons move.
What part of the atom occupies all the volume?
Almost all of the volume of an atom is the space between the nucleus and the electrons.
What contributes the most volume of an atom nuclear or electron cloud?
The electron cloud contributes the most volume of an atom. While the nucleus contains most of the atom's mass, it occupies a very small space compared to the vast area of the electron cloud, where electrons are found. The electron cloud's size is determined by the energy levels and orbitals of the electrons, making it the dominant contributor to the overall volume of an atom.
Why does an electron take up a lot of volume in an atom?
due to high velocity it occupies a very lage volume arround a nuclius..
What make up the most of the volume of atom?
Most of the volume of an atom is vacuum.
What make up most of the volume of an atom.?
Most of the volume of an atom is vacuum.
Describe the experimental basis for believing that the nucleus occupies a very small fraction of the volume of the atom?
The experimental basis for believing that the nucleus occupies a very small fraction of the volume of the atom comes from the results of the Rutherford gold foil experiment. In this experiment, alpha particles were fired at a thin gold foil, and most particles passed straight through, indicating that the nucleus, where most of the atom's mass is concentrated, is very small compared to the overall size of the atom. This led to the development of the planetary model of the atom, where electrons orbit a small, dense nucleus.
What is the Volume of an atom is occupied by the?
Most of the volume in an atom is occupied by the electron cloud. Most of the complex reactions of the atom occur in the cloud.
What is the answer toThe amount of space that matter occupies is referred to as?
The amount of space that matter occupies is its volume.
What occupies a small amount of the total space inside an atom?
Electrons occupy a small amount of the total space inside an atom. They are negatively charged particles that move around the nucleus, which contains protons and neutrons. The majority of the volume within an atom is actually empty space.
How many F atoms are needed to occupy the same volume as a Cs atom?
Since the volume of an atom is determined by the radius of its electron cloud, we can use the atomic radius to approximate the volume each atom occupies. The atomic radius of Cs is larger than that of F, so more F atoms would be needed to occupy the same volume as one Cs atom. Approximately 9 F atoms are needed to occupy the same volume as one Cs atom.
Does each sample occupies space?
Yes, each sample of a substance occupies space due to its physical dimensions and the volume it occupies in a container. The amount of space a sample occupies is known as its volume.
