A molecule is a collection of two or more atoms that are securely bound together by attractive forces or by chemical bonds. The term “atom” refers to the tiniest unit of matter that can be separated. The term “valency” refers to an element’s capacity for combination. ...
atom with 6 neutrons and 6 protons in its nucleus so that its mass number is 12. c) mass = 12 u q9. an element form an oxide al 2 o 5 . (i) what is the valency of element a? (ii) what will be the formula of the chloride of the element? answer. the formula of the oxide...
Mass and radio- activity alone seem to depend directly upon this hitherto unsuspected and all-important nucleus. The chemical and physical properties, including the light spectrum, are governed probably by the outermost shell or ring of valency electrons, which 3:lone are variable in number. The...
Most atoms, when embedded in a low-density jellium model of a metal, are expected to form negative ions, whereas of course metallic atoms release their valency electrons when embedded in their own free-electron gas. The reason is that there is a critical electron density above which the ...
Revolution of the stable groups of electrons would add to the stability of the molecules formed by their combination and increase the directional steadiness of the valency forces. In this way it may be possible to reconcile Langmuir's theory with that of Bohr....
(b) The valency of the elements or ions and this must be balanced in formula (c) when a compound consists of a metal and a non-metal, the name or symbol of the metal is written first (d) in compounds formed with polyatomic ions, the ion is enclosed in a bracket before writing the...
The result of bond formation is molecule and its energy will be less than the sum of the energy of the constituent atoms. So in terms of stability atoms tempts to form bonds.Answer and Explanation: Valency of an atom In the simplest sense val...
How many valence electrons are there in chlorine and what is its valency? Each Group 16 element has how many valence electrons? a. 4 b. 6 c. 8 d. 16 An ion with a charge of +4 has two electrons with n=1, eight e...
(c ) Eclectronic configuration : 2,8,3 , (d) Valency (e ) the name o f the element , (f) its nature whether metal or non metal View Solution Given that the N shell of an element contains 10 electrons, write the electronic configuration of the stable ion. View Solution What woul...
Answer and Explanation:1 The atoms of the same groups have similar electronic configuration of the valence shell therefore the valency of these atoms is similar. Due to their... Learn more about this topic: Electron Configurations in the s, p & d Orbitals ...
