the idea behind rutherfords atomic theory is that the atom has a central positive nucleus and negatively charged electrons, which move in orbits, surround it. most of the atom is made up of empty space. he assumed this theory through a gold-foil experiment about which you can find information on the internet.
What else can I help you with?
What did Ernest Rutherford add to are knowledge of atoms?
Ernest Rutherford's gold foil experiment led to the discovery of the atomic nucleus and the proposal of the nuclear model of the atom. He demonstrated that atoms are mostly empty space with a dense, positively charged nucleus at the center. This helped pave the way for further understanding of atomic structure and the development of the modern atomic theory.
What year did Ernest Rutherford add to our knowledge?
Ernest Rutherford contributed significantly to our understanding of atomic structure in the early 20th century. His famous gold foil experiment in 1909 led to the discovery of the atomic nucleus.
What did Rutherford add to the atomic model?
He discovered that an atom has a very dense and very tiny positively charged nucleus. He named the positively charged particles protons.
How is the atomic weight of an element found?
you add the number of protons (the atomic number) to the number of neutrons
What atomic number of f plus the atomic number of Na equals the atomic number of what element?
Calcium=Ca=Atomic number 20 9+11=20

What do you have to add to get the atomic number?
The atomic number is equal solely to the number of protons in an atom.
How is the atomic weight of an element found?
you add the number of protons (the atomic number) to the number of neutrons
Do you have to add the protons and electrons in order to find the atomic mass of an atom?
no, you add the protons and neutrons
How do you find the atomic mass of C7H8?
You mean molecular mass or moler mass, not atomic mass! Add up the atomic masses of all the atoms in the molecule.
How do you find the atomic mass and the atomic number?
The atomic number is the whole # on the periodic table or the # of protons in an atom. The atomic mass is the # that is not the whole # on the periodic table, or you can multiply the mass of the isotope by its abundance and add the answers together.
What is the cost-plus-markup theory?
Cost-plus-markup theory is the theory that business firms calculate their unit costs and add on a percentage markup.
The atomic number is the same as the number of these two particles?
The "Atomic number" of an element corresponds to the number of only the protons in the nucleus of its atoms. Add to that the number of neutrons that are also in there, and you have the "Atomic weight".
What is percent abundance?
Take percent abundance times atomic mass for each isotope then add all up for average atomic mass.
What is it called when you add a depressant to alcohol?
a bad idea.
