Where in the atom is most of its mass concentrated?
Approximately whole mass of the atom is concentrated at the centre known as nucleus. Approximately 99.99% of the mass of the atom is concentrated at the centre or you can say nucleus. Nucleus contains protons and neutrons. Protons have positive charge and neutrons have no charge. So, nucleus has positive charge while electrons have negative charge.
Were is most of the mass located of an atom?
This experiment showed that most of an atom is empty space, but there is a very small, dense nucleus in the center which has almost all the mass of the entire atom. Later Rutherford discovered positively charged protons in the nucleus of the atom.
Where is most of the mass of an atom located?
The positively charged center of that atom where most of the mass of the atom is located nucleus The negatively charged area around the nucleus where the volume of the atom is located electron cloud One characteristic of a metal is shiny One characteristic of a nonmetal is dull
What is atomic mass and how is it determined?
The atomic mass of the atom is the mass of the protons plus the mass of the neutrons, 6 + 7, or 13. 3) Weighted Average for All Atoms of an Element The atomic mass of an element is a weighted average of all the element's isotopes based on their natural abundance. It is simple to calculate the atomic mass of an element with these steps.

Where is the mass of an atom concentrated?
Therefore, the mass of an atom would be mainly the mass of the protons and neutrons, which are found in the nucleus of an atom, so we can say that the mass of an atom is concentrated mainly in the nucleus.
What is the mass of an electron?
A proton and a neutron are both assumed to have a mass of 1 u, while an electron has a mass of 1 1836 u, so a lot of teachers would say that the mass of an electron is close to nothing or 0 u.
Where is the mass of an atom concentrated?
Almost the entire mass of the atom is concentrated in the Almost the entire mass of the atom is concentrated in the nucleus, which occupies only a tiny fraction of the atom's volume.
Where is the proton located in an atom?
the proton atom is located in the nucleas of the atom. the neutron is located in the nucleas of the atom to. the electron is located around the outside of the nucleas .
What is the arrangement of the parts of an atom?
The arrangement of the parts of an atom, which consists of a massive, positively charged nucleus surrounded by a cloud of electrons arranged in orbits describable in terms of quantum mechanics.
Where is the valence energy level of electrons located?
the valence energy level of electrons are located in the outer region of the eletron cloud
Which scientist discovered that particles are not the smallest particles?
J.J thomson discovered that are not the smallest particles.
Which theory states that electrons orbit the Sun?
In the modern atomic theory an electron's exact location cannot be determined, while in Bohr's atomic theory have set paths around the nucleus basically like how the planets orbit the Sun.
What are the subatomic particles found inside the nucleus?
They include neutrons. They are subatomic particles found inside the nucleus. They include protons.
Which orbital is said to belong to the same?
All orbitals with the same value of the principal quantum number and the secondary quantum number are said to belong to the same...
What is the energy needed to remove an electron from a gaseous atom?
Ionization energy is the energy that is needed in order to remove an electron from a gaseous atom or ion.
What happens when an electron drops from a higher to lower orbit?
The energy released when an electron drops from a higher to lower orbit appears as a photon with energy equal to the energy difference between the two orbits. Electron moves around the nucleus along orbits.
What is the average atomic mass of chlorine?
The mass 35.453 is the average atomic mass of an atom of chlorine.
What is the charge that creates a magnetic field?
The "revolving" charge, or spin, creates a magnetic field.
