Electronegativity increases from left to right across a period in the periodic table and decreases down a group. The electronegativity values derived by Pauling follow predictable periodic trends, with the higher electronegativities toward the upper right of the periodic table. Thus, the nonmetals,...

One purpose is to obtain a set of consistent homolytic bond dissociation energies (BDE) for establishing accurate trends across the periodic table. The main objective is to elucidate the underlying physical factors behind these chemical bonding trends. On one hand, we confirm that, along a period...

The ITR metric is calculated by looking at the current emissions intensity of companies within the fund's portfolio as well as the potential for those companies to reduce its emissions over time. If emissions in the global economy followed the same trend as the emissions of compan...
Why does the electronegativity decrease from top to bottom as a trend in the periodic table? Why does sand conduct heat better than water? What is the pH of a 0.250 M solution of methylamine ( CH_3NH_2, K_b=4.4 \times 10^{-4}...
Bond energy (E) is defined as the amount ofenergyrequired to break apart amoleofmoleculesinto its componentatoms. It is a measure of the strength of a chemical bond. Bond energy is also known as bond enthalpy (H) or simply as bond strength. ...
