One of the key technical differences between the forex markets is the way currencies are quoted. In the forwards or futures markets, foreign exchange always is quoted against the U.S. dollar. This means that pricing is done in terms of how many U.S. dollars are needed to buy one unit of the other currency.
Neutrons and protons make up the nucleus of an atom. They make up the mass of the atom. The volume of an atom is made up of electrons which move outside the nucleus Describe the parts of the atom and where they are found. Neutral atoms have the same number of electons (negative) and protons (positive).
Atoms consist of electrons [electrons: Sub-atomic particles, with a negative charge and a negligible mass relative to protons and neutrons. ] surrounding a nucleus [nucleus: The central part of an atom. It contains protons and neutrons, and has most of the mass of the atom.] that contains protons protons: Sub-atomic particles with a positive charge and a relative mass of 1. and neutrons neutrons: Uncharged sub-atomic particles, with a mass of 1 relative to a proton. .eutrons are neutral, but protons and electrons are electrically charged. Protons have a relative charge of +1, while electrons have a relative charge of -1. The number of protons in an atom is called its atomic number.
