Where on the periodic table are the non metal?

The nonmetals or non-metals are a group of elements located on the right side of the periodic table (except for hydrogen, which is on the top left). These elements are distinctive in that they typically have low melting and boiling points, don't conduct heat or electricity very well, and tend to have high ionization energies and electronegativity values.

Hydrogen is the most abundant element, with oxygen, carbon, and nitrogen, being the third, fourth and seventh elements respectively. Nitrogen and oxygen make up most of the earth’s atmosphere, with nitrogen making up 78% and oxygen about 21%. The four mass elements in the human body are other non-metals, such as oxygen (65%), carbon (18%), hydrogen (10%), and nitrogen (3%). Oxygen is the most abundant non-metallic element in the earth’s crust.

Do nonmetals have a shiny surface?

It also doesn’t have the shiny “metallic” character associated with metals. Nonmetals tend to form brittle solids. Nonmetals tend to easily accept electrons to fill their electron shells, so their atoms often form negatively charged ions.

Why do we have a periodic table?

“If you memorize the periodic table it will speed you up if you’re a chemist, but by and large, the reason you have a periodic table is so that you can store that information outside of your body. That way it frees up some part of your brain to do something else.”.

Is a non-metal a solid?

So, non-metals are brittle instead of solid. And they are not ductile (you cannot make them into thin wires) or malleable (they can not be made into thin sheets. And, instead of easily losing electrons as metals do, non-metals gain them through chemical reactions. Apart from this, some non-metals are liquid.

Is mercury a solid or liquid?

Metals are solid, with the sole exception of Mercury (Hg), which is liquid. All metals conduct heat and electricity, and they all have a shiny appearance. All metals can be made into thin wires, this feature is technically known as ductility.
