Whenever moving from left to right in a period, metallic character _____________.

Correct option is B

• As we move from left to right across a period in the periodic table, the metallic character decreases.
• This is because, as we move across a period, the nuclear charge increases (more protons in the nucleus), pulling the electrons more strongly toward the nucleus, making it harder for the atoms to lose electrons.
• Metallic character is associated with an atom’s ability to lose electrons and form positive ions (cations). As this ability decreases across a period, the metallic character decreases.
• On the other hand, non-metallic character increases as you move from left to right.

•  Elements on the left side of a period (such as alkali metals) exhibit strong metallic properties.
• Elements on the right side of a period (like halogens and noble gases) are more non-metallic, meaning they gain electrons more easily than lose them.
