That would be the noble gases
It nonmetal ! I know this one! I had it on a worksheet!
nonmetals
it's called a non metal
The most metallic element after francium is cesium. Cesium is located in Group 1 of the periodic table and has properties that are characteristic of metals, such as high electrical conductivity and metallic luster.
Non metals
most metals are metallic in a way. the periodic table consists of 3 different types of elements metals, non metals and metalloids the most metallic are the metals because they posses the most metal like properties.
the most important properties in an element is state at room tempreture
Calcium is the element that has the most properties in common with magnesium on the periodic table. Both elements are in Group 2, known as the alkaline earth metals, and share similar physical and chemical properties such as high reactivity and the ability to form ionic compounds.
Density
Their properties are similar with non-metals and metals. That's why they're called semi-metals. They are reactive depending on the element they are reacting with, and they are semi-conductors.
A metalloid is a chemical element with properties that are in-between or a mixture of those of metals and nonmetals, and which is considered to be difficult to classify unambiguously as either a metal or a nonmetal.
Calcium is an element that behaves most like magnesium due to their similar chemical properties. They are both alkaline earth metals, have similar reactivity, and form similar compounds.
