State how electrons are distributed in an atom. Explain in brief the rules which govern their distribution.
If an atom 'A' has atomic number 19 & number 39, state -
(i) Its electronic configuration.
(ii) The number of valence electrons it possesses.
'Valency' is the number of hydrogen atoms which can combine with [or displace] one atom of the element [or radical] forming a compound. With reference to the above definition of valency, state the valency of chlorine in hydrogen chloride, giving reasons.
'Valency' is also the number of electrons - donated or accepted by an atom so as to achieve stable electronic configuration of the nearest noble gas'. With reference to this definition -
(a) State what is meant by 'stable electronic configuration'.
(b) State why the valency of -
(i) sodium, magnesium & aluminium is: +1, +2 & +3 respectively.
(ii) chlorine, oxygen & nitrogen is: -1, -2 & -3 respectively.
