An atom X has three electrons more than the noble gas configuration. What type of ion will it form?

An atom has two electrons more than the noble gas configuration. What type of ion will it form?

Assertion Among two cations of similar size the polarising power of cation with pseudo noble gas configuration is larger than cation with noble gas configuration Reasoning Polarising power of Ag^(o+) is more than K^(o+) .

Assertion :NiO is less than CaO. Reason : Ni^(2+) is pseudo noble gas configuration cation whereas Ca^(2+) is noble gas configuration cation.

In the atom of an element X, 6 electrons are present in the outermost shell. If it acuires noble gas configuration by accepting requisite number of electrons, then what would be the charge on the ion so formed ?

Which of the following represents noble gas configuration?

How does xenon atom form compounds with fluorine even though the xenon atom has a closed shell configuration ?

Fill in the blank by selecting a correct word given in the brackets. Atoms combine to form chemical bonds and attain electronic configuration like their nearest __________ .(nonmetals/noble gases)
