electron level or orbital
In chemistry, a shell refers to the energy level where an electron is located within an atom. Electrons are arranged in shells around the nucleus of an atom, with each shell having a maximum capacity of electrons it can hold. Shells are also referred to as electron shells or energy levels.
It could be the element Phosphorus, the p orbitals in an atomic shell, etc.
Electrons in the outermost shell are called valence electrons.
According to my chemistry book (Chemistry: The Molecular Nature of Matter and Change by Silberberg) seashells including clam shells are primarily composed of Calcium Carbonate.
"Chemistry" is done by the outer valance shell of electrons, NOT by the nucleus.
Open shell compounds are typically more reactive than closed shell compounds because open shell compounds have unpaired electrons, making them more prone to participate in chemical reactions to achieve a stable electron configuration. Closed shell compounds have all electrons paired and are generally more stable and less reactive.
The element with 4 valence electrons in its L shell is carbon. Carbon has an atomic number of 6, which means it has 6 electrons. These electrons are distributed in two shells: the first shell (K shell) holds 2 electrons, and the second shell (L shell) holds the remaining 4 electrons, making carbon a key element in organic chemistry.
In chemistry, the octet and duplet rules are part of electronic configuration. The octet rule is when the outermost shell has 8 valence electrons. The duplet rule is when the outermost shell has 2 valence electrons, e.g. Helium and Hydrogen.
The electron shell is also called the principle energy level in chemistry and atomic physics. The shells starting closest to the nucleus names go from shell 1 or shell K, shell 2 or shell L,shell 3 or shell m, etc. Each shell contains a certain amount of electrons the first shell starts with two and the number increases for each shell.
Silicon needs four covalent bonds to fill its outer shell and achieve a stable electron configuration, similar to carbon in the context of organic chemistry.
Florine have only 2 shells namely 1s and 2s is is inner and 2s is outer shell I there is any question related to chemistry then ask me....
In chemistry, "ns" typically stands for the principal quantum number for electrons in the outermost electron shell of an atom. It helps to define the energy levels and spatial distribution of electrons within an atom.
