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...

Fill in the blank: Nonmetals form negative ions by (losing/gaining) ___ enough electrons to achieve the electron configuration of the next noble gas.Give the number of electrons the atoms of each of the following elements wants to gain...
Which of the following options is correct? The chemical reactivity of an element is largely determined by a. the number of protons in the nucleus of the atom. b. the number of neutrons in the nucleus of the atom. c. the nu...
The design included k2 factorial points completed by 2k axial points and a center point, where k is the number of variables. Thereupon, CCD and RSM were applied in order to evaluate the association between the variables, i.e., percentage of sawdust (%), pH of the sawdust, and contact ...
