elements are not regarded as transition w elements? w 10 UNDERSTANDING fus H vap H AND a H In transition metals unpaired (n - l)d electrons as well as ns electrons take part in interatomic bonding. Larger the number of unpaired (n - 1) d electrons‚ the stronger is the interatomic bonding and large amount of energy is required to overcome the interatomic interaction. ∆ fus Hθ M(s) → M(1) θ ∆ vap H M(1) → M(vapour) ∆a Hθ M(s) → M(g) These enthalpies are related as fus

Laboratory 9 Lab title: Conductivity of solutions and Household Items PURPOSE: To understand the compounds that dissociate (break into ions) when dissolved in water. Determine ionic compounds are electrolytes. To identify solutions as electrolytic and non-electrolytic‚ and to identify variations in conductivity among electrolytes. Substances that are capable of conducting an electric current in solution are known as electrolytes. Substances that do not conduct an electric current

Learning Goal: To understand how the scientific method can be used to search for explanations of nature. The scientific method is a procedure used to search for explanations of nature. The scientific method consists of making observations‚ formulating hypotheses‚ designing and carrying out experiments‚ and repeating this cycle. Observations can be either quantitative or qualitative. Quantitative observations are measurements consisting of both numbers and units‚ such as the observation that ice melts

Interactions between subunits of a protein containing a quaternary structure are usually weak interactions such as hydrogen bonding‚ ionic bonding‚ and van der Waals. It is important to note that quaternary structures can be simple such as two identical subunits or even complex where dozens of different polypeptide chains come
