It indicates the protons. Periodic table is based on atomic number.


How is the Rutherford model different from previous models?

Rutherford's model for the atom, based on the Geiger-Marsden experiment results, contained the new features of a relatively high central charge concentrated into a very small volume in comparison to the rest of the atom and with this central volume also containing the bulk of the Atomic Mass of the atom. later this is called as nucleus.


What identifies atomic number?

Periodic table is based on atomic number.It represents protons in a atom.


What element is the atomic base unit amu based off of?

The atomic mass unit (amu) is based on the carbon-12 isotope, with 1 amu defined as one twelfth of the mass of a carbon-12 atom. This definition allows for easier comparison of the masses of different atoms.


What is the atomic number based on in the nucleus?

The atomic number is based on the number of protons in the nucleus of an atom. It determines the element's identity on the periodic table.


What is the need of atomic models?

Atomic models tell us about the structure of an atom which is based on what we know about how atoms behave. But it is not necessary that it will be a genuine picture of the structure of an atom.


What does it mean to say the atomic number in an atom?

The atomic number of an atom is the number of protons in its nucleus. It determines the element's identity on the periodic table and is used to arrange elements in ascending order based on their properties.


The atomic number is based on what?

It is based on number of protons. Consider an element has 20 protons.Its atomic number is twenty.


Sub atomic particle with an atomic mass unit of 1?

Either a proton or neutron has an atomic mass of 1. An electron's mass is actually extremely small in comparison. The majority of the weight of an atom is in the nucleus.


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.


Atomic mass of an atom is determined by the weight of?

The atomic mass of an atom is determined by the total number of protons and neutrons in its nucleus. Protons and neutrons contribute to the majority of an atom's mass, electrons have negligible mass in comparison. The atomic mass unit (amu) is used to express atomic mass, with 1 amu approximately equal to the mass of a proton or neutron.
