Question

How do the elements of the second group having valence shell electronic configuration ns² show paramagnetism when they do not have unpaired electrons?

Q. Assertion :Alkali metals are paramagnetic but their salts are diamagnetic. Reason: Alkali metals are elements having 1 valence electron is s-subshell. As it has one unpaired electron, the salts of alkali metals are formed by bonding of their valence electrons as they do not have unpaired electrons.

Q. The group in which all the elements do not have same number electrons in their valence shell is :

Q. Noble gases do not react because they have __________ electrons in their valence shell.

Q. When elements are placed in the order of their increasing atomic number,
the elements having the same number of __________ is repeated in such a way, so as to fall under the same group. Since, the electronic configuration of the valence shell electrons is same they show similar properties.

Q. Assertion :Elements in the same group show same valency. Reason: As the outermost electron is added in the same valence shell as they share the same electronic configuration.
