Basics of Chemistry Part-04   (Valancy, charge & ions ) In the previous three parts of this series, we have learnt about details of first 20 elements, calculated their atomic weight, drawn their atomic structures and learnt about shell & sub-shell electronic configurations. Not seen Part-1, Part-2 & Part-3 yet?? Click here for Basics of Chemistry || Part-01 || Click here for Basics of Chemistry || Part-02 ||   Click here for Basics of Chemistry || Part-03 || In this part we will be discussing about valencies and radicals of the first 20 elements about which we have studied in previous parts. We will first learn to calculate valencies from shell and sub-shell electronic configurations and then we will be looking towards ions. So, let us start without any delay... After understanding shell electronic configuration, it is easy to predict valencies of the elements just by looking their last number. For example, the Electronic configuration (E.C.) of Lithium i...

Basics of Chemistry Part-03   (Shell and Sub-shell Electronic configuration ) In the previous two parts of this series, we have learnt about details of first 20 elements, calculated their atomic weight and drawn their atomic structures.  Not seen Part-1 and Part-2 yet?? Click here for Basics of Chemistry || Part-01 || Click here for Basics of Chemistry || Part-02 || In this part we will be discussing about shell(orbit) and sub-shell(orbital) electronic configuration of first 20 elements. We will learn how to write these electronic configurations and what information can be obtained from them. So, let us start... As we have seen in the atomic structure, the first shell (orbit) can accommodate maximum 2 electrons, we will first try to put 2 electrons in 1st orbit i.e., K-Shell (orbit). But, Hydrogen contains only 1 electron as a whole, so it contains only 1 electron in the 1st shell (Orbit). Then, the 2nd orbit i.e., L-Shell can accommodate maximum 8 electrons. So, we will ...

Basics of Chemistry Part-02   ( Atomic structure of f irst 20 elements) In the previous part we learnt about details of first 20 element and we calculated atomic weight of them. That was the first and most important step in studying chemistry. Without understanding about elements, their symbol and valancy, it is impossible to understand chemistry. So, for that, we have to first draw and understand the atomic structure of all first 20 elements. Click here for  Basics of Chemistry || Part-01 || So, let us start... Atomic Structure of first 20 elements Atomic Structure of Hydrogen (H) Atomic Structure of Helium (He) Atomic Structure of Lithium (Li) Atomic Structure of Beryllium (Be) Atomic Structure of Boron (B) Atomic Structure of Carbon (C) Atomic Structure of Nitrogen (N) Atomic Structure of Oxygen (O) Atomic Structure of Fluorine (F) Atomic Structure of Neon (Ne) Atomic Structure of Sodium (Na) Atomic Structure of Magnesium (Mg) Atomic Structure of Aluminum (Al) Atomic Struct...

Syllabus of PCL Nursing by CTEVT

By Pravin Keshari
Image
Syllabus of PCL Nursing by CTEVT Nepal Government has adopted a national policy for the attainment of health "Health for all beyond the Year 2000 A.D." through the use of primary health care approach. As a result CTEVT got the mandate to produce middle level trained workforce through CTEVT as well as CTEVT affiliated institutions. During the process of curriculum development the Nepal Government has endorsed the concept of gerontology care, because the PCL nursing graduated are prominent service providers; the Department of Health has suggested incorporating this new emerging health issue in the curriculum. Likewise the psychiatric nursing theory and clinical hours has increased, similarly a new subject called Basic Science Applied to Nursing has been added that consists of Biochemistry (Microbiology, Parasitology & Virology) and Pharmacology. Some portions of oncology nursing is also has been added in the curriculum. The course is conducted both in theoretical and practi...
