Higher reactivity
WebpKa differences and reactivity. I know a lot of chemists like to quote p K a values and subtract them to reinforce some notion about some acid-base reaction being highly favorable or highly unfavorable or whatnot. For example, the p K a of acetic acid is about 5 and the p K a of LDA's conjugate acid is about 36. 36 minus 5 gives us 31 "zeros ...

Higher reactivity
Did you know?
Reactivity is a somewhat vague concept in chemistry. It appears to embody both thermodynamic factors and kinetic factors—i.e., whether or not a substance reacts, and how fast it reacts. Both factors are actually distinct, and both commonly depend on temperature. For example, it is commonly asserted that the reactivity of group one metals (Na, K, etc.) increases down the group in the periodic table, or that hydrogen's reactivity is evidenced by its reaction with oxygen. In fac… Web2 de jun. de 2024 · More pertinent in our highly reactive times is dynamic emotional reactivity — a negative emotion in one party of an interaction that causes a negative emotion in the other, such that the...
Web6 de set. de 2024 · Among the halogens, fluorine, chlorine, bromine, and iodine, fluorine is the most reactive one. It forms compounds with all other elements except the noble gases helium (He), neon (Ne) and argon (Ar), whereas stable compounds with krypton (Kr) and xenon (Xe) are formed. WebThe periodic table shows that metals are found in groups 1, 2 and 3. These metals will have 1, 2 or 3 electrons in the outer shell. The outer shell of a metal is, therefore, less than half full of ...
