PASSAGE - IV : In periodic table metals show high reducing ability and non-metals show high oxidizing ability. The properties of metalloids in between metals and non-metals. In a group from top to bottom the reducing ability increases and in a period from left to right oxidizing ability increases. In which of the following set both are metalloids

Nuclear charge increase both in a period and group. But, effective nuclear charge increase in a period and decreases in a group. Identify the correct reverse trend.

List out the properties of elements which increase in a group from top to bottom as well as in a period from left to right.

In a period from left to right A) nuclear charge increases B) effective nuclear charge increases C) atomic size decreases D) Ionisation potential increases Correct among the above are

The bromine atom possesses 35 electrons. It contains 6 electrons in 2p orbital, 6 electrons in 3p orbital and 5 electrons in 4p orbital. Which of these electrons experience the lowest effective nuclear charge ?

Assertion (A) : Na^+ and Mg^2+ ions are isoelectronic but the ionic radius of Na^+ is greater than the of Mg^2+ . Reason (R) : The effective nuclear charge of Na^+ ion is less than that of Mg ^2+ ion.

(A) : Mg^(2+) and Al^(3+) are isolectronic but the magnitude of ionic radius of Al^(3+) is less than that in Mg^(2+) . (R ) : The effective nuclear charge on the outermost electrons in Al^(3+) is greater than that in Mg^(2+) .

(A) : Salts of Mg does not impart any colour to the flame (R): Due to small size and high effective nuclear charge, 'Mg' requires a large amount of energy for excitation of electrons.
