Question

Describe the metallic and non-metallic properties of periods.​

pls give answer in quick time

Answer 1

Answer:

Explanation:

Metallic character refers to the level of reactivity of a metal. Non-metallic character relates to the tendency to accept electrons during chemical reactions. ... Non-metallic tendency increases going from left to right across the periodic table.

Answer 2

Physical properties associated with metallic character include metallic luster, shiny appearance, high density, high thermal conductivity, and high electrical conductivity. Most metals are malleable and ductile and can be deformed without breaking.

The elements which have a tendency to gain electrons are known as non-metals. The tendency to gain electrons increases on moving across a period due to an increase in the nuclear charge and decrease in the atomic size. Hence, the non-metallic character increases across a period.

If helped pls drop a thanks
