A nonmetal
is an element that lacks most of the properties of a metal. All of the elements in the shaded boxes are nonmetals. Many of the nonmetals are common elements on Earth. In general, the physical properties of nonmetals are the opposite of those of metals.

Which of the following elements is not a metal?
The nonmetals list which makes up the periodic table includes hydrogen, helium, carbon, sulfur,
nitrogen
, oxygen, radon, neon, other halogens, and noble gases etc. When we study the elements, it is important to know which elements are metals and which ones are not.
What are the elements under metals?
Most elements are metals. This group includes
alkali metals, alkaline earth metals, transition metals, basic metals, lanthanides
(rare earth elements), and actinides. Although separate on the periodic table, lanthanides and actinides are really specific types of transition metals.

What are the properties of nonmetals and metalloids?
N onmetals
are elements that lack most of the properties of metals. I There are 17 nonmetals, each located to the right of the zigzag line in the periodic table. In general, the physical properties of nonmetals are opposite to those that characterize the metals.

Is K metal or nonmetal?
The chemical symbol K comes from kalium, the Mediaeval Latin for potash, which may have derived from the arabic word qali, meaning alkali. Potassium is a soft,
silvery-white metal
, member of the alkali group of the periodic chart.
Is Si a metal?
Silicon the semiconductor
Silicon is neither metal nor non-metal; it’s
a metalloid
, an element that falls somewhere between the two.
What are the 3 types of metals?
There are three main types of metals
ferrous metals, non ferrous metals and alloys
. Ferrous metals are metals that consist mostly of iron and small amounts of other elements. Ferrous metals are prone to rusting if exposed to moisture.
