Electronic configurations
All the alkali metals have one electron in their outermost 's' orbitals preceded by the noble gas configuration. Thus, the general configuration of alkali metals may be written as [Noble gas] ns 1 where 'n' represents the valen..
Electronic configuration
Like halogens, hydrogen has only one electron less than the nearest noble gas configuration. H : 1s 1 He : 1s 2 F : 1s 1 2s 2 2p 5 Ne : 1s 1 2s 2 2p ..
Atomic Properties Electronic Configuration
The relative abundance of noble gases along with their electronic configurations is given in the table. Electronic configurations of noble gases Element Symbol Atomic No. Electronic Configuration Abunda..
Noble gases or Aerogens
These consist of gaseous elements of group 18, the last group in 'p' block. All noble gases have a general outermost electronic configuration of 'ns' and 'np'. The only exception is helium having an outermost configuration of 1s 2 . Because they display thes..
4. Electron affinities
(i) All these have maximum electron affinities in their respective periods. This is due to the fact that the atoms of these elements have only one electron less than the stable noble gas (ns 2 np 6 ) configurations. Therefore, may have maximum tend..
Electronic Nature of Metals and Non-metals
The tendency of an atom to take part in chemical combination is determined by the number of valence electrons (electrons in the outermost shell of an atom). The atoms acquire the stable noble gas configuration of having eight electrons in ..
Third Row Elements
The third row elements are from sodium to argon. The build up of these eight elements proceeds exactly in the same manner as discussed above. Here 3s- and 3p-orbitals are filled in place of 2s- and 2p-orbitals as has been done in case of Li to Ne. For e.g., the electronic configura..
Oxidation States
Halogens have only one electron less than the next noble gas. Therefore, they can get the noble gas configuration either by gaining one electron to form uninegative ion, X - , or by sharing electrons with other at..
Bonding in Carbon - The Covalent Bond
Although there are more than hundred elements around us we do not find these elements in their native form in nature. This is because most of these elements are highly reactive. They interact with each other to form simple or complex substances. Only elements with the noble gas..

Very good, Tutor was clear and guided me through the whole algebra problems
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
Tutor Vista tutors actually helped me to think through some of the problems instead of just doing them for me.Now i am more confident with math ,Thank you all
