Generally, when going down a group on the periodic table: a. atomic radii decrease b. ionic radii increase c. electronegativity increases d. reactivity decreases The trend for atomic radius as you move down a family on the periodic table is for the atomic radii to increase...
Describe the periodic trend of electronegativity. Generally, when going down a group on the periodic table: a. atomic radii decrease b. ionic radii increase c. electronegativity increases d. reactivity decreases What is the general trend of electronegativity as you go left to right ...
The analysis of the dipole moments and of the bonding contributions from all electron Hartree-Fock wavefunctions clearly shows that in MO alkaline-earth diatomic molecules (M 顥 Mg, Ca, Sr, Ba) the degree of ionic character increases as MgO < CaO < SrO < BaO. This is the trend ...
The misfit layered Bi2A2Co2O8 (A = Ca, Sr, Ba) compounds experience an insulator to metal transition as A’s ionic radius increases. This feature is contradictory to the conventional wisdom that larger lattice constant favors insulating rather than
Steven Pinker on “The False Allure of Group Selection” A recurrent idea in Steven Pinker’s essay is that group selection “adds little to what we have always called ‘history’.” I argue, on the contrary, that cultural multi-level selection (CMLS) provides a highly productive theoretical...

The obtained ranges of values show that the sensitivity of 𝐸bEb and 𝑑𝜋⋯𝜋dπ⋯π to the basis set used increases with increasing size of the noble gas atom, i.e., in the order He→Ne→Ar→Kr. These ranges, however, are negligible in relation to the average value, as ...
Downloadkeyboard_arrow_down Browse Figures Versions Notes Abstract The fertilization of freshwater fish occurs in an environment that may negatively affect the gametes; therefore, the specific mechanisms triggering the encounters of gametes would be highly expedient. The egg and ovarian fluid are likely ...
Before reaching this point, the loading stress increases with increasing strain, but after the peak point, the material faces deformation. In this region, the stress values usually decrease with increasing strain values. Figure 4a,b represents such types of stress–strain relationships of the ...
