The table shows some properties of the elements in group 4 of the periodic table.
| Element | Period | Appearance | Melting point in °C | Electrical conductivity of the solid |
|---|---|---|---|---|
| carbon (diamond) | 2 | colourless, transparent | 3550 | does not conduct |
| silicon | 3 | shiny grey-black | 1414 | poor |
| germanium | 4 | shiny grey-white | 938 | poor |
| tin | 5 | shiny silver | 232 | good |
| lead | 6 | shiny grey | 327 | good |
State why all these elements are placed in group 4.
Silicon has atomic number 14. Give the electronic configuration of silicon.
Describe how the properties of the elements change down group 4. Use data from the table.
A student says, "Tin and lead are metals because they are shiny." Evaluate the student's statement. Use data from the table.
Flerovium is the element below lead in group 4. Predict whether flerovium is a metal or a non-metal. Give a reason for your answer.
