There are six metalloids, boron, silicon, germanium, arsenic, antimony, and tellurium
The only generally accepted metalloid that has three electrons in its outermost shell is Boron - symbol B - electronic structure 1s22s22p1 .
Aluminium is a metalloid
Carbon, Silicon (a metalloid), Germanium (a metalloid),
Boron, silicon, and arsenic are all members of Group 15 of the periodic table, also known as the nitrogen group. They are nonmetals (boron is a metalloid) with varying properties. Boron is the first element in the group, silicon is a metalloid with semiconducting properties, and arsenic is a metalloid with some similarities to a metal.
No, argon is not a metalloid. It is catagorized as a noble gas.
Boron is the only mettaloid in Group 13
A group 5 metalloid that is quite versatile is antimony. It is often used in tractor bullets, as fireproofing material and for infrared detection.
No, oxygen is not a metalloid. Oxygen is a nonmetal, located in group 16 of the periodic table.
Whatever row the element is in on the periodic table is the energy level, so the answer would be the metalloid in the third row, which is silicon (Si).
Belgian musical group Lasgo was formed in the year 2000 and currently has three members. Those three are Jelle Van Dael, Peter Luts, and Jeff Martens. The group's former members include Evi Goffin and Dave McCullen.
Germanium is a metalloid. It has some properties of both metals and non metals. It belongs to group 14.
Tellurium (Te) is a metalloid. It is a p block element and belongs to group 16
