Heisenberg along with Schrodinger formulated Quantum Mechanics, it is the theory that replaces classic Newtonian mechanics in the world of atoms and molecules. Heisenberg also played a significant role in propelling the world into the nuclear age. After the war, German scientists including Heisenberg took credit for diverting the regime from pursuing a bomb, for moral as well as practical reasons.

Which pairing does not correctly match the scientist with the contribution to the understanding of the atom?

The pairing of Isaac Newton with the contribution to the understanding of the atom is incorrect. Newton was primarily known for his work in physics and mathematics, particularly his laws of motion and universal gravitation, which were foundational to classical mechanics. The understanding of the atom was more significantly influenced by scientists like John Dalton, J.J. Thomson, and Ernest Rutherford.


Which particles in an atom contribute most to mass of the atom?

The particles are protons, neutrons, and the nucleus inside of the atom Nice helping u >_<


When particle in a atom is responsible for its chemical properties?

This is the number of protons.


Why don't we count electrons in determining the atomic mass?

Electrons have such a small mass relative to protons and neutrons that they are typically not included in calculations of atomic mass. The mass of electrons is about 1/1836 of the mass of a proton or neutron, so their contribution to the overall mass of an atom is negligible. Instead, atomic mass is primarily determined by the sum of the number of protons and neutrons in the nucleus of an atom.


What is the effective atomic number of water?

The effective atomic number of water is approximately 7.42. This value takes into account the contribution of the hydrogen atoms in water in addition to the oxygen atom. It is a way to characterize the overall electron density of the molecule.
