The third type of signal recorded in ice cores is encoded in the pure ice itself. Ice, or more generally water, is made up of two atoms of hydrogen and one atom of oxygen. Naturally occurring hydrogen and oxygen both come in rare heavier forms called isotopes (see sidebar). In sea wa...
1 (a)Chemists recognise that atoms are made of three types of particle.Complete the following table with their names and properties.name of particle relative mass relative charge+11/18363(b)Most elements exist naturally as a mixture of isotopes, each with their own relative isotopic mass. The ...
Oxygen is made up of two oxygen atoms that are covalently bonded. Hydrogen (H2)- This is the simplest and the first element in the periodic table. Its two hydrogen atoms are covalently bonded. Naturally, it occurs in three isotopes, namely: protium, tritium and deuterium. Therefore, it is...

Some examples of monatomic ions are sodium ions and hydrogen ions that have positive charges. Hydride ions, chloride ions, and oxide ions are a few examples of monatomic anions.What Is a Monatomic Ion? The term Monatomic ion sounds complex. The meaning becomes clear if taken as three parts....
This study targeted the carbonate karst reservoirs of the Ordovician Ma5 Member in the southeastern Ordos Basin. Based on the analysis of cores, thin sections, cathodoluminescence, scanning electron microscopy (SEM), carbon and oxygen isotopes and trace elements, we discuss the development ...
aCertain types of nuclear reaction are possible,where certain light unclear particles can be combined,or fuse,into heavier particles.Such reactions produce pure energy.The most attractive feature here is that commom elements such as hydrogen isotopes can be used as fuel ,making this source essential...
An atom in turn is a microscopic collection of protons, neutrons and electrons in some combination. Hydrogen, the simplest atom, consists of only a proton and an electron; uranium, the most massive, has 92 protons, 92 electrons and 146 neutrons in one of its isotopes. An atom usually has...
