Chapter Name : The P- Block Elements |
Sub Topic Code : 102_11_11_06_04 |
Topic Name : Group 14 Elements: The Carbon Family |
|
Sub Topic Name : Electronegativity |
• Due to small size, the elements of this group are slightly more electronegative than group 13 elements. • The electronegativity values for elements from Si to Pb are almost the same.
Elements, periodic table, Group, electronegativity
• Group 14 has carbon, silicon which is found in the earth’s crust. • Carbon dating is done by using the C-14 isotope.
