Question

State the property trends in general on moving from left to right in a period of the periodic table

July 25, 2024

Answer

The property trends in general on moving from left to right in a period of the periodic table are :

Number of valence electrons — increases by one
Atomic radius — decreases.
Ionization potential — increases.
Electron affinity — increases (exception, electron affinity is zero for noble gases).
Non-metallic character — increases.
Metallic character — decreases
Electronegativity — increases (with the exception of noble gases, they have complete octet so do not attract electrons to itself).

Periodic table

Match the elements in column ‘X’ with the correct group they belong from column ‘Y’
X Y
1: Element with atomic number 19 A: Group 18 [0 group]
2: Element with electronic configuration 2 B: Group 16 [VI A]
3: Element with a valency of -2 C: Group 1 [IA]
4: Element ‘P’ which loses 3 electrons to form a cation D: Group 17 [VII A]
5: Element ‘Q’ in period-3 which has the highest electron affinity E: Group 13 [III A]

Periodic table

With reference to group 1 [IA] of the periodic table – fill in the blanks with the correct word:
The elements are …………… [light/heavy] …………… [metals/non metals] since their atomic size is …………… [large/small]. The energy binding the atoms is …………… [high/low] and hence the elements have …………… [high/low] melting points. The melting points of the elements …………… [increases/decreases] down the subgroup. The electropositive character …………… [increases/decreases] down the subgroup and the elements are strong …………… [reducing/oxidizing] agents.
