Electropositive nature of the element(s) increases down the group and decreases across the period
(b) Electronegativity of the element decreases down the group and increases across the period
(c) Atomic size increases down the group and decreases across a period (left to right)
(d) Metallic character increases down the group and decreases across a period.
Based on the above trends of the Periodic Table, answer the following about the elements with atomic numbers 3 to 9.
(e) Name the element which shows maximum valency.
Solution:
(a)The electropositive character of the element(s) increases as it progresses through the group and diminishes as it progresses through time.
(b) The element’s electronegativity drops as it moves down the group and increases as it moves across the period.
(c) Atomic size reduces as one moves down the group and grows as one moves up the period (left to right)
(d) The metallic character grows as the group progresses and reduces as the period progresses.
e) Carbon is the element that shows maximum valency.
