Question

why metallic property of element decreases from left to right ​

Answer 1

Answer:

When we move across a period from right to left in the periodic table, the metallic character of elements decreases. This happens because atoms of elements across a period from right to left accept electrons more readily to fill their valence shell.

Answer 2

$\huge\star{\red{\underline{\mathfrak{Answer:-}}}}$

Along the period, from left to right, the effective nuclear charge increases due to increase in no. of protons due to which forces of attraction b/w nucleus and valence electrons increases and ability to lose electrons (i.e metallic character) decreases.
