Atomic and ionic radii
The atomic and ionic radii of alkaline Earth metals are smaller than the corresponding members of the alkali metals. This is due to the fact of Group 2 elements having a higher nuclear charge allow electrons to be attracted more towards the nucleus. This red..

The distance from the nucleus to the outermost shell depends on the electrostatic attraction (nuclear charge) that the nucleus exerts on the electrons of the outer shell. More the nuclear charge closer are the shell and electrons, hence smaller is the atomic radius of ..

The atomic and ionic radii of group 13 elements are compared to corresponding elements of group 2. This is due to the increase in nuclear charge when one moves from, element of group 2 to group 13 in the same period. As the elements are c..
Atomic and ionic radii
The atomic and ionic radii of group 15 elements are smaller than the atomic radii of the corresponding group 14 elements. This is because of increased nuclear charge. On going down the group, the atomic radii increase due to the..
Atomic radii
Fig: 4.3 - Calculation of atomic radius The inter-nuclear distance corresponds to the diameter of the atom and therefore half of this distance gives the atomic radius for a homonuclear molecule like Cl-Cl or Br-Br. Hence, it may be defined as one ha..
Stoichiometric (or empirical) Formulae of Ionic Compounds
The electrostatic field of an ion is nondirectional.Each positive ion attracts several negative ions around it depending upon its size or radius and vice-versa ,resulting in a three dimensional solid aggregate called an ionic crystal in which oppositely charged ions alternate i..

I really liked this tutoring. Helped me alot and gave me more ways to work a problem. awesome help and I even got the idea on these problems - kimi
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
My grades increased drastically with Tutor Vista and I'll definitely recommend this to all students who want to do better in their school. Not only do we learn, we also have fun!
Looking for More Help!
