mostly diatomic non-metal gas which is odourless and colourless in nature. since it has five electrons in its outer shell, most of its compounds are trivalent. it is a constituent of all living tissues. since it is a component of dna and part of a genetic code, it is an essential elem...
Nitrogen is a nonmetal, with an electronegativity of 3.04. It has five electrons in its outer shell and is therefore trivalent in most compounds. The triple bond in molecular nitrogen (N2) is the strongest. The resulting difficulty of converting N2 into other compounds, and the ease (and asso...
Nitrogen has many uses. It is the second most commonly produced chemical in the UnitedStates. Its chemical and physical properties, along with the five electrons in its outer shell,make it a versatile element that can react as a metal or nonmetal to produce numerous compounds.Some of its uses...
The five outer shell electrons screen the nuclear charge quite poorly, showing that the effective nuclear charge felt at the covalent radius distance is relatively high. Thus, nitrogen atoms are relatively small in size and high in electronegativity, being intermediate between carbon and oxygen in ...
(ii) Hydrazine, N2Ha, is another compound of nitrogen and hydrogen.Complete the diagram to show the electron arrangement in a molecule of hydrazine,showing only outer shell electrons.H HN NH H[3](d) Nylon and proteins are both polymers containing nitrogen.(i) Name the linkages found in ...
Besides hydrogen, what element wants 2 valence electrons in its outer shell? Can you balance Zn(No3)2 + NH4Br = ZnBr2 + NH4NO3? Is NH3 an acid anhydride? Why can an isotope be substituted for the common version of the same ...
Free radicals, reactive oxygen species (ROS) and reactive nitrogen species (RNS) are molecules or molecular fragments containing one or more unpaired electrons in atomic or molecular orbitals, which characterises free radicals with high reactivity (Halliwell and Gutteridge, 1999). ...
Choose one of the following elements (C, H, O, N), and answer questions 1-6 on it: - Atomic Number - Mass Number - Number of electrons in the outer shell - Number of protons - Number of electrons - Number of...
D1 The two N atoms in an N2 molecule are held together by a very strong triple bond.2 The triple bond between two N atoms is not polar. The bonds in O2 and Cl2 are polar.3 The atoms in N2 have a full outer shell of electrons. The atoms in O2 and Cl2 do not have a full ...
These core electrons do not participate in the chemical bonding and core electrons are tightly bound to the nucleus. Answer and Explanation: The correct option is e. The total number of electrons in phosphorus is 15. Out of these 15...
