Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atomâthe Na+ cation. Carbon is the 15th most abundant element in the Earth’s crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. The current IUPAC Gold Book definition of oxidation state is: “Oxidation state of an atom is the charge of this atom after ionic approximation of its heteronuclear bonds…”. Carbon is one of the few elements known since antiquity. Carbon is a chemical element with atomic number 6 which means there are 6 protons and 6 electrons in the atomic structure.

Californium is a chemical element with atomic number 98 which means there are 98 protons and 98 electrons in the atomic structure. Elements with high ionization energies have high electronegativities due to the strong pull exerted by the positive nucleus on the negative electrons. Your email address will not be published. Carbon compounds generally show 4 reactions, they are Combustion reaction; Oxidation reaction, Addition reactions; Substitution reaction. The chemical symbol for Carbon is C. It is nonmetallic and tetravalentâmaking four electrons available to form covalent chemical bonds. The chemical symbol for Titanium is Ti. In general, an atom’s electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The metal is found in the Earthâs crust in the pure, free elemental form (ânative silverâ), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Arsenic is a metalloid. The chemical symbol for Nobelium is No. Four important chemical reactions are discussed below: Combustion Reactions: When Carbon and its compounds burn in the presence of Oxygen (or air), they give CO2, heat and light.The process of burning carbon and its compounds in excess of oxygen for the release of heat and light (energy) is known as combustion. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure. It is the eponym of the lanthanide series, a group of 15 similar elements between lanthanum and lutetium in the periodic table, of which lanthanum is the first and the prototype. Tellurium is far more common in the universe as a whole than on Earth. Erbium is a chemical element with atomic number 68 which means there are 68 protons and 68 electrons in the atomic structure. Carbon is the 15th most abundant element in the Earth’s crust, and the fourth most abundant … Nobelium is a chemical element with atomic number 102 which means there are 102 protons and 102 electrons in the atomic structure. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. It is the heaviest element that can be formed by neutron bombardment of lighter elements, and hence the last element that can be prepared in macroscopic quantities. Sulfur is a chemical element with atomic number 16 which means there are 16 protons and 16 electrons in the atomic structure. Bromine is a chemical element with atomic number 35 which means there are 35 protons and 35 electrons in the atomic structure. At 0.099%, phosphorus is the most abundant pnictogen in the Earthâs crust. This variation is typically small for solids and liquids but much greater for gases. The chemical symbol for Cerium is Ce. We have also distinguish between the possible and common oxidation states of every element. The chemical symbol for Einsteinium is Es. The chemical symbol for Niobium is Nb. The answer is that when a saturated hydrocarbon is burnt in the presence of oxygen than it gives blue colour flame and this is because here fuel is burnt completely. For example, carbon has nine possible integer oxidation states from â4 to +4. This is because when carbon or diesel is burnt in air, it produces a large amount of heat energy.

The chemical symbol for Scandium is Sc. Such weak intermolecular bonds give organic molecular substances, such as waxes and oils, their soft bulk character, and their low melting points (in liquids, molecules must cease most structured or oriented contact with each other). Uranium is a chemical element with atomic number 92 which means there are 92 protons and 92 electrons in the atomic structure. See also: Densest Materials of the Earth.
