Question

An element of group 14 has an atomic number of 14. Explain whether this element will have metallic properties or non metallic properties. [3 MARKS]

Answer 1

Each point: 1 Mark

1. The element is Silicon (Si). It has 14 electrons and its electronic configuration is 2, 8, 4.
2. The element has to lose or gain 4 electrons to attain octet.
3. Since it is difficult for Si to lose or gain electrons, it is classified as a metalloid. It exhibits some metallic properties and some non metallic properties.
