Chemical Properties of Non-Metal
- 4-8 electrons in the outer shell: Basically, the non-metals outer shell has 4 to 8 electrons, and thus it has the tendency to attract electrons.
- Can gain electrons: Non-Metals can form charge ions by gaining their electron when reacting with a metal.
- Form acidic oxides: Non-Metal can form acidic oxides when reacting with oxygen.
- Have high electronegativities: Since we have already discussed what is electronegativity, and we know in non-metals there are 4-8 electrons present in the outer shell thus it has more ability to gain electrons. Thus, we can say that non-metals have high electronegativity.
Properties of Metals and Non-Metals
Metals and Non-metals have different properties and reactivity with other elements. This difference between the physical and chemical properties of elements depends on their position in the periodic table. The physical properties of substances (or elements) include tendencies like conductivity, density, malleability, ductility, lustrousness, physical state, etc. Moreover, the chemical properties of elements can include reactions with other elements and compounds, in order to check their reactivity, also include electronegativity, etc. Here is the periodic table showing metals, non-metals, and metalloids at different position and are highlighted with different colors, as shown below:
