Question

3. Explain the tendency of metallic property in elements of Group and Period.​

Answer 1

Answer:

Metallic character decreases as you move across a period in the periodic table from left to right. This occurs as atoms more readily accept electrons to fill a valence shell than lose them to remove the unfilled shell. Metallic character increases as you move down an element group in the periodic table.

Answer 2

In the group, metallic property in elements increases, and in the period metallic property decreases.

• In the modern periodic table, there are 18 groups and 7 periods.

• Metallic property is the tendency of an element to lose electrons and remove its unfilled valence shell and become a stable element.

• Metallic property in elements increases from top to bottom in the group. Because as we go top to bottom in a group, ionization enthalpy decreases, and electrons get easily lost from the outermost shell. Consequently, the tendency of the metallic property increases down the group.
• In period, metallic property in elements decreases because as we move from left to right in the periodic table, atomic size decreases due to an increase in nuclear charge as a result ionization enthalpy increases in the period which leads to an increase in the tendency of an element to accept electrons and become a non-metal by decreasing its metallic character and increasing its non-metallic property across the period.
