Xenon reversibly complexes gaseous M(CO) 5, where M=Cr, Mo, or W. p-block metals also bind noble gases: XeBeO has been observed spectroscopically and both XeBeS and FXeBO are predicted stable. [27] The compound Xe 2 Sb 2 F 11 contains a Xe–Xe bond, the longest element-element bond known (308.71 pm = 3.0871 Å). [28]
In the Indian education system of some Indian states, the Pre-University Course (PUC) or Pre-Degree Course (PDC) is referred to as intermediate or +2 course, which is a two-year senior secondary education course that succeeds the tenth grade (known as SSLC or SSC in such states, equivalent to sophomore in the US system) and precedes to the completion of a Senior Secondary Course.
The inert-pair effect is the tendency of the two electrons in the outermost atomic s-orbital to remain unshared in compounds of post-transition metals.The term inert-pair effect is often used in relation to the increasing stability of oxidation states that are two less than the group valency for the heavier elements of groups 13, 14, 15 and 16.
The p orbital can hold a maximum of six electrons, hence there are six columns in the p-block. Elements in column 13, the first column of the p-block, have one p-orbital electron. Elements in column 14, the second column of the p-block, have two p-orbital electrons. The trend continues this way until column 18, which has six p-orbital electrons.
