The periodic trends

Periodic trends are changes in the properties of chemical elements along the periodic table of elements. Major periodic trends include electronegativity, ionization energy, electron affinity, atomic radius, ionic radius, metallic character, and chemical reactivity.

The periodic trends in properties of elements

These trends reflect the changes in atomic properties along the periods (horizontal rows) and groups (vertical columns) in the periodic table. They give a qualitative assessment of the properties of each element. However, not all properties strictly follow these trends, for example, the ionization energies in group 3, the electron affinities in group 17 or the densities in group 1 elements (alkali metals).

Varicose Veins

Varicose Veins Varicose veins are swollen blood vessels that appear just under your skin’s surface in your lower body. When your vein walls are weak and your valves aren’t working right, blood backs up in your vein. This causes the blue and purple bulges you see on your legs, feet or ankles. Several treatment options can work, but varicose veins can return. Varicose veins look blue or purple below the skin. What are varicose veins? Varicose veins are swollen, twisted blood vessels that bulge just under your skin’s surface. These blue or purple bulges usually appear in your legs, feet and ankles. They can be painful or itchy.

Although they can be unsightly and uncomfortable, varicose veins aren’t dangerous for most people. In some cases, severe varicose veins can lead to serious health problems, such as blood clots.
