8
Why is carbon the foundation of a whole field of chemsitry (organic chemistry?)
Because the university hates me
Catenation
Because we're made of carbon and we're organic
Carbon can bond to itself and form stable chains and rings

Why does group 2A have higher ionization energies than Group 1A(1) elements
Both larger and higher effective nuclear charge
Group 2A is smaller
Group 2A is bigger
They have higher effective nuclear charge
