Which element has the same number of valence electrons as oxygen (O)? Fire uses oxygen to oxidize compounds typically of carbon and hydrogen to water and carbon dioxide (although other elements may be involved) whether in uncontrolled conflagrations that destroy buildings and forests or the controlled fire within engines or that supply electrical energy from turbines, heat for keeping buildings warm, or the motive force that drives vehicles. B. Nitrogen is a constituent element of amino acids and thus of proteins, and of nucleic acids (DNA and RNA). With nitrogen it forms alkaloids, and with the addition of sulfur also it forms antibiotics, amino acids, and rubber products. Within a period, protons are added to the nucleus as electrons are being added to the same principal energy level. Whilst this is straightforward for some molecules such as Cl 2 and O 2, in other cases one has to infer the covalent radius by measuring bond distances to atoms whose radii are already known (e.g., a C--X bond, in which the radius of C is known). Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure. SURVEY . Tags: Question 3 .

Atomic Radius is defined as the distance between the center of the nucleus and the outermost shell of an atom. [35][36] The simplest carbon-containing molecules are the hydrocarbons, which contain carbon and hydrogen,[35] although they sometimes contain other elements in functional groups. [30] 13C is also stable, with six protons and seven neutrons, at 1.1%. Oxygen is part of substances best described as some salts of metals and oxygen-containing acids (thus nitrates, sulfates, phosphates, silicates, and carbonates. The element which has the largest atomic radius is Cesium. On the periodic table, atomic radius generally decreases as you move from left to right across a period (due to increasing nuclear charge) and increases as you move down a group (due to the increasing number of electron shells). Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. 228 times. Which element in the second period has the greatest atomic radius?
