Which of the following sequence of explanation is appropriate for explaining the reason for the periodicity of reducing property in a period or group? (1) Tendency to undergo oxidation decreases in a period and increases in a group (2) In a period ionisation energy increases and in a group it decreases. (3) In a period the atomic size decreases and in a group it increases. (4) The elements present in the left side of the periodic table have strong reducing property.

1.	Which of the following sequence of explanation is appropriate for explaining the reason for the periodicity of reducing property in a period or group? (1) Tendency to undergo oxidation decreases in a period and increases in a group (2) In a period ionisation energy increases and in a group it decreases. (3) In a period the atomic size decreases and in a group it increases. (4) The elements present in the left side of the periodic table have strong reducing property.
Answer» (a) 3 2 1 4 (b) 3 4 2 1 (c) 4 3 1 2 (d) 4 2 1 3 Solution :(1) In a period the ATOMIC size decreases and in a group it increases. (2) In a period ionisation ENERGY increases and in a group it decreases. (3) Tendency to undergo oxidation decreases in a period and increases in a group. (4) The elements present in the LEFT side of the PERIODIC table have strong reducing property.
