Metallic Character
The ability of an atom to donate electrons and form positive ion (cation) is known as electropositivity or metallic character. Down the group, metallic character increases due to increase in atomic size and across the period, from left to right electropositivity decreases due to decrease in atomic size.
Non-Metallic Character
The ability of an atom to accept electrons to form a negative ion (anion) is called non-metallic character or electronegativity. The elements having high electro-negativity have a higher tendency to gain electrons and form anion.Down the group, electronegativity decreases due to increase in atomic size and across the period, from left to right electronegativity increases due to decrease in atomic size

Hydrogen is placed along with Alkali metals in the modern periodic table though it shows non-metallic character

Options

A. as Hydrogen has one electron & readily loses electron to form negative ion.
B. as Hydrogen can easily lose one electron like alkali metals to form positive ion.
C. as Hydrogen can gain one electron easily like Halogens to form negative ion.
D. as Hydrogen shows the properties of non metals.

Answer

B

Explanation

Hydrogen is placed along with Alkali metals in the modern periodic table though it shows non-metallic character as Hydrogen can easily lose one electron like alkali metals to form positive ion.
