The electron configuration of an atom is the representation of the arrangement of electrons distributed among the orbital shells and subshells. Commonly, the electron configuration is used to describe the orbitals of an atom in its ground state, but it can also be used to represent an atom that has ionized into a cation or anion by compensating with the loss of or gain of electrons in their subsequent orbitals. Many of the physical and chemical properties of elements can be correlated to their unique electron configurations. The valence electrons, electrons in the outermost shell, are the determining factor for the unique chemistry of the element.
The Four Electronic Quantum Numbers
Quantum numbers designate specific shells, subshells, orbitals, and spins of electrons. This means that they describe completely the characteristics of an electron in an atom, i.e., they describe each unique solution to the Schrödinger equation, or the wave function, of electrons in an atom. There are a total of four quantum numbers: the principal quantum number (n), the orbital angular momentum quantum number (l), the magnetic quantum number (ml), and the electron spin quantum number (ms). The principal quantum number, n n , describes the energy of an electron and the most probable distance of the electron from the nucleus. In other words, it refers to the size of the orbital and the energy level an electron is placed in. The number of subshells, or l l , describes the shape of the orbital. It can also be used to determine the number of angular nodes. The magnetic quantum number, ml, describes the energy levels in a subshell, and ms refers to the spin on the electron, which can either be up or down.
The plasma membrane is also known as the cell membrane. It is the boundary between the internal components of a cell and its external surroundings. It controls the entry and exit of substances into or out of the cell and thus, facilitates the exchange of substances between the cells and their external environment.
Since rubella vaccine is made from duck eggs if the client has an egg allergy, an allergic reaction may occur. Which would be a reason to cancel the rubella vaccination.
This is because the nervous system would no longer be linked to the endocrine system.
The reason as to why the adrenal and thyroid glands atrophy if the pituitary glands cease to function is because the nervous system would no longer be linked to the endocrine system.
Thyrotrophic and adrenocorticotrophic hormones from the anterior pituitary keep the adrenal and thyroid glands in action. If pituitary stops secreting them, it is obvious that adrenal and thyroid would be affected.
