Protons, neutrons, and electrons.
Protons and neutrons are the baryons present in the nucleus.
Protons have a positive charge, and a mass of approx. 1 amu.
Neutrons have no charge, and a mass of approx. 1 amu.
Electrons are leptons with negative charge and negligible mass, and are found in orbitals outside the nucleus.
Not all atoms have neutrons (such as in the case of hydrogen-1).
Variation in electron number defines the ionization state of the atom (more electrons than protons gives a negative ion, less electrons than protons gives a positive ion).
Proton number separates one element from another.
What else can I help you with?
What are the three main parts of an electrons address used in the current atomic theory that describe an electrons location?
I think you are referring to the 3 quantum numbers, n, l m; principal azimuthal and magnetic. Together with the spin quantum number they "define" an electron- but I would hesitate to call this the electrons location- Heisenbergs uncertainty principle gets in the way of a simultaneous knowledge of energy and location.
In the wave - mechanical model of the atom orbitals are regions of the most probable locations of?
In the wave-mechanical model of the atom, orbitals are regions of space where there is a high probability of finding an electron. These orbitals define the three-dimensional shape and size of the space where an electron is most likely to be located.
If the principle quantum number is 3 what possible values can azimuthal quantum number have?
For a principle quantum number 3, there are three possible sub-shells. These are 3s, 3p, 3d. Azimuthal quantum no. is less than principle quantum number. There for 3s it is 0, for 3p it is 1, for 3d it is 2.
Can two electron have the same set of quantum number?
Pauli's exclusion principle
The Quantum Number that defines the shape of space an electron most likely resides in is the quantum number.?
The quantum number that indicactes the shape of an orbital in called the angular momentum quantum number.
What are the three subatomic models?
The three subatomic models are the plum pudding model, the nuclear model, and the current model known as the quantum mechanical model. These models describe the structure of the atom and the arrangement of subatomic particles within it.
What are the three main parts of a compound microscope?
The compound microscope has three main parts, The three main parts of a microscope includes the illuminating parts, the magnifying parts, and the mechanical parts.
What are the three parts of the digestive system?
mechanical, chemical, and peristalsis wich are enzymes
List the four possible subshells in the quantum-mechanical model?
First of all: The Bohr Atom interpretation (this wasstill very classical and not very quantummy). After that came (in chronological order): Heisenberg's Matrix Mechanics, Shrodinger's Wave Mechanics, and the best, Richard Feynman's and Julian Shwinger's "Quantum Electro-Dynamics" which eventually became the now widely accepted "Quantum Electro-Weak Theory" encompassing the weak force as well as photons and electrons. Hope this helps.
What are the three general parts of microscope?
The three general parts of a microscope are the eyepiece (ocular lens), the objective lens, and the stage where the specimen is placed and viewed. These parts work together to magnify and focus light onto the specimen for observation.
Who were the three scientists that discovered the wave mechanical model?
The three scientists who played a major role in developing the wave mechanical model of the atom were Erwin Schrödinger, Werner Heisenberg, and Max Born. Their work revolutionized our understanding of the behavior of electrons in atoms.
