the compound we call water is created by combining the elements hydrogen and oxygen. One molecule of water is always made up of two hydrogen atoms and one oxygen atom. This is why water is referred to as H₂O in science. Water is created when elements chemically...
Summary – Element vs Molecule The key difference between element and molecule is that elements consist of only a single type of atoms while molecules may contain two or more atoms of the same element or different elements. The properties of an element often change completely when they are part...
b) Structure of the compound (individual molecules vs. lattice) c) What kind of elements pres What is the name of a chemical bond in which a hydrogen atom of one molecule is attracted to an electronegative atom, especially a nitrogen, oxygen, or fluorine atom, usually of another...
atom系一种element入面最细而且不能分割的部份,而Ion是由于atom/molecule得到或者失去electron时而令atom/molecule中的正负电荷失衡,得到净正或负电荷,咁ion都系element入面最细而且不能分割的部份?polyatomic ion系多过一个 atom 的 ion,咁他算不算系compound?

[5]and a proper functioning of the biosensors requires the presence of an intermediary compound, a so-called mediator, which shuttles redox equivalents between the recognition element and transducer. This supplementary step in the biosensing chain usually results in the increase of the biosensor’s...
