Oxygen
The element with the highest first ionization energy in group 14 is carbon.
Carbon has the highest ionization energy
the nobles gases are the greatest ionization group
Element 115 on most modern periodic charts.
Fluorine. Ionization energies are a periodic trend and they generally increase as you go up and to the right in the periodic table.See the chart in the Web Links to the left for a complete chart of the ionization energies of all the elements.
Nitrogen
No. Carbon and Nitrogen are different elements themselves. They don't contain any element within them.
Halogens, specially fluorine
Yes, the daughter element of Carbon-14 isNitrogen-14.
After carbon, The element having largest number of compounds is Hydrogen.
And hydrogen and oxygen and nitrogen
Nitrogen makes up 75% of the air followed by carbon dioxide and oxygen
