A valence electron is an electron in the outer shell (or cloud or orbital as it is sometimes referred) farthest away from the nucleus. These are the electrons that are transferred or shared in chemical bonding. (A "full" outer shell refers to atoms with (usually) 8 electrons in its outer shell.)
Valence electrons are electrons that are on the outside "shell." In Group (column) 1, there is only one valence electrons for each element. In Group (column) 2, there are two valence electrons. Group 13: 3 valence electrons Group 14: 4 valence electrons Group 15: 5 valence electrons Group 16: 6 valence electrons Group 17: 7 valence electrons Group 18: 8 valence electrons There is no Group 19, so this list is done. For the metals, each element will need to be mapped out utilizing the Bohr Diagram design or something of the like as valence electrons are difficult to define due to the grouping on the periodic table. The most valence electrons that can be in an outer shell is eight. Barium (Ba) is in Group (column) 2, and thus has only two valence electrons.
Ionization energy is the amount of energy required to remove one electron from a neutral atom in the gaseous state. It is a measure of how tightly the electron is held by the nucleus of the atom. Elements with higher ionization energies require more energy to remove an electron and are less likely to form ions.
The boundary of an electron cloud represents the region where there is a high probability of finding an electron. It helps define the size and shape of the atom or molecule, influencing its chemical properties and interactions with other atoms. The boundary also signifies the extent of the electron's influence on the surrounding environment.
Lewis defined acids as substances that are electron pair acceptors, and bases as substances that are electron pair donors. According to Lewis, acids and bases react by sharing an electron pair to form coordinate covalent bonds.
MgOMagnesium: 2 Valance Electrons (Charge is +2)Oxide: 6 Valance Electrons (Charge is -2)Hint: Oxide has a charge of -2 and so does Oxygen. Check the periodic table for the elements that have a -2 charge (group 16) and you will find oxygen as the first element in that group. Periods define how many energy levels the element has, just so you know. Oh and this is ionic.Hope this helps!
a group of atoms ith an unpaire electron
Fermi level is that level where the probability of finding the electron is exactly half. it lies between the conduction and the valence band.. its helps in formation of extrinsic substance... also in finding the good recombination agent for a different combination's it is also used in various calculations and determining probability of finding electron
Mass and charge are not connected. Negative charge is the charge carried by an electron.
Its actually electron pair repulsion. Its the principle that electron pairs around a central atom tend to orient themselves as far apart as possible. Electron pair repulsion is used to predict the geometry of a molecule or a polyatomic ion.
It is a measure of how easily an electron cloud is distorted by an electric field. Electron cloud will belong to atom, molecule or Ion. It is the quantitative measurement of the extent to which the electronic cloud can be polarized
The different areas of an electron cloud are called electron orbitals. These orbitals define the regions in an atom where electrons are most likely to be found. They are categorized by different shapes and energies based on quantum mechanics.

Yes, quantum numbers define the energy states and the orbitals available to an electron. The principal quantum number (n) determines the energy level or shell of an electron, the azimuthal quantum number (l) determines the shape or orbital type, the magnetic quantum number (m) determines the orientation of the orbital, and the spin quantum number (+1/2 or -1/2) determines the spin state of the electron. Together, these quantum numbers provide a complete description of the electron's state within an atom.
Size on the scale of atoms is very hard to define. The electron has zero mass. Quarks have varying amounts of mass.

An electron volt (eV) is a unit of energy equal to the energy gained by an electron as it moves through a potential difference of one volt. It is commonly used in atomic and subatomic physics to describe the energy of particles at the atomic and molecular scale.
