"Valence electrons are the outer electrons that are involved in bonding. Only electrons in the s and p orbitals are valance electrons, so a given atom can have between 0 and 7 valance electrons. Atoms ...

"States of matter are the different phases which matters can take - gas, liquid and solid. Gas has no fixed shape and conforms to the volume of its container. A liquid has a distinct volume but assume ...

"There are two main exceptions to electron configuration: chromium and copper. In these cases, a completely full or half full d sub-level is more stable than a partially filled d sub-level, so an elec ...

"Electron configuration is shorthand for the arrangement of electrons in atomic orbitals. It is written out, as opposed to orbital diagrams which are depicted pictorially. For elements with many elect ...
"The electromagnetic spectrum depicts different frequencies of electromagnetic radiations shown from blue to red. On the electromagnetic spectrum, wavelength is shown to be increasing to the right and ...

"All electrons have four quantum numbers which describe the location of electrons in the electron cloud of an atom. The principle quantum number (n) describes the size of the orbital the electron is i ...

"The law of conservation of mass states that mass is neither created nor destroyed. In a closed system, mass of reactants is equal to mass of products. The law of conservation of mass is related to th ...

"Planck's constant, abbreviated h, is the ratio of photon energy to the frequency. Planck's constant is used in the blackbody radiation spectrum, which indicates that energy is carried by light in dis ...

"The photoelectric effect is a tool that we use to determine how much energy electrons have. The photoelectric effect was explained by Albert Einstein in 1905 and states that when light shines on meta ...

"Changes in matter can be classified as either physical or chemical, like matter properties. Physical changes include changes in physical appearance but not composition. All changes in state of matter ...
