Question

The elements with atomic number 3-10 belong to the second period. Taking into account the trends in the general periodic properties predict (1) the most electronegative element (2) the most electropositive elements (3) the elements which constitute the large number of organic compound

Answer 1

lithium i.e, 3 is the most electronegative element ,Carbon i.e, 6 constitute the large no. of organic compound

Answer 2

Answer:

1) Fluorine

2) Lithium

3) Carbon

Explanation:

1) fluorine is the most electronegative element known, as per the modern periodic table. it has the highest affinity towards electrons in its valence shell, as it requires only one electron to attain octet structure.

2) lithium is the most electropositive element as the nuclear force between the shells and nucleus (positive charge) is very strong, as it has to lose only one electron to attain stability.

3) carbon can combine with various elements and is a basic constituent of organic compounds.
