What is used to show electrons in an atom?
Four quantum numbers are used to describe electrons in atoms.
What were atoms and how do they behave?
Atoms are things that make up elements and compounds Their behaviour varies depending on their state. Atoms in solids vibrate but don't move around Atoms in liquids move around but stick together. Gas particles are very free and they shoot about in the air
Names and symbols of the four quantum numbers required to define the energy of electrons in atoms?
These are: principal quantum number (n), azimutal quantum number (ł), magnetic quantum number (m), spin quantum number (sd).
What do these valence electrons do that make them are so important in chemistry?
the number of valence electrons determine the reactivity of the atoms
How is an orbital principal quantum number related to the atoms major energy levels?
The principal quantum number describes the size of the orbital. Because they have opposite electrical charges, electrons MORE.
How do you determine location of an electrons atoms?
use the quantum theory
What is the modern description of the electrons in atoms?
There are two main models used today one being the bohr model and then there's the quantum mechanical modal
Which scientist developed the quantum mechanical model of the atoms?
Erwin Schrodinger
What is used to show electrons in an atom?
Four quantum numbers are used to describe electrons in atoms.
Which model of the atom shows electrons traveling around the nucleus in wave patterns?
The Bohr Model, and its the basis of quantum theory
How do electrons move around the atoms nucleus?
In orbitals, quantum mechanical statistical clouds that can each hold a maximum of 2 electrons (one spin up, one spin down).
Molecular orbital theory is based upon which model of the atom?
Molecular orbital theory determines molecular structure that the electrons are not assigned as individual bonds between atoms, however, are treated as moving under the influence of the nuclei in the whole molecule.

What quantum model mean?
the modern description, primarily mathematical, of the behavior of electrons in atoms
Names and symbols of the four quantum numbers required to define the energy of electrons in atoms?
These are: principal quantum number (n), azimutal quantum number (ł), magnetic quantum number (m), spin quantum number (sd).
What is the force that hold atoms together in a covalent bond?
Covalent bonds are held together by electrostatic (+/-) attractions between the nucleus of one atom and electrons from another atom and vice versa and there is also a quantum mechanical effect of delocalisation.
What are the circular patterns around the nucleus?
Although commonly depicted as circular orbits in simple diagrams of atoms, this is incorrect. The electrons occupy statistical quantum mechanical "clouds" called orbitals, each of which can contain no more than two electrons (if fully occupied the two electrons in the orbital must have opposite spin states).
