This contribution extends the pioneering work of Z.-Z. Yang et al. [Yang ZZ, Davidson ER (1997) Int J Quantum Chem 62:47–53; Zhao DX, et al. (2018) Mol Phys 116:969–977] by our consideration of the ...

It is shown here that in cobalt and zinc niobates, cobalt, zinc and oxygen ions have Golden ratio based ionic radii, whereas in lead niobate, all atoms have covalent radii.

Atomic and ionic radii increases down the group due to the addition of a new shell at each step. NCERT Exemplar Questions and Solutions Class 12 Chemistry Ionisation enthalpy ...

ABSTRACT: The germicidal properties of some metals and metal compounds were investigated in relation to their electro-chemical properties that may play a role in the inactivation of E. coli bacteria.

(i) The general electronic configuration of alkaline earth metals is [noble gas] ns 2. (ii) The atomic and ionic radii of alkaline earth metals are smaller than that of alkali metals.

Understanding the mechanical properties of materials is crucial for engineering applications. Poisson's ratio., which measures a material's lateral strain response to uniaxial stress., and the average ...
