VALENCY Valency can be defined as the combining capacity of an element.The electrons present in the outermostmost shell of an atom are known as valence electrons and they determine the valency.The valence electrons take part in chemical reaction and they determine the chemical properties of the elements.Let us take an example‚ Theatomic number of carbon is 6 Its configuration is =2‚4 It means valency of carbon is 4. In chemistry‚ valence‚ also known as valency or valence number‚ is the number

faced by the steel industry Introduction 3 Challenges faced by the steel industry 3 Conclusion 13 Work cited During the 1950s‚the European steel market‚ steel production and import unrelentingly augmented. This created surplus provisions on the promotion of the Six. Due to this‚ there was deterioration of the market together with its selling value. This drop continued as a result of antagonism from inexpensive introductions from eastern nations. Therefore‚ the European steel industry was

populations of six economically important species in the genus Brassica have unusual potential for resolving many problems in plant biology and for use in education. Rapid-cycling brassicas can produce up to ten generations of seed per year and serve as models for research in genetics‚ host-parasite relations‚ molecular biology‚ cell biology‚ plant biochemistry‚ population biology‚ and plant breeding.
