Respuesta :
The option (b) is correct - it have the highest ionization energies.
What is ionization energy?
In physics and chemistry, the amount of energy needed to remove an electron from a single atom or molecule is known as the ionisation energy or ionisation potential.
What is alkaline earth group ?
Because of the "alkaline" solutions, hydroxides, that they produce when they interact with water, these metals are known as "alkaline" earth metals. The oxides of alkaline earth metals were known to alchemists as "earth."
The alkaline earth group atoms are found in group 2A of the periodic table. The smaller they are (further up the group), the closer the valence electrons are to the nucleus. Since the nucleus is positively charged and electrons are negatively charged, there is electrostatic attraction between them.
Electrostatic attraction increases in strength the closer together the oppositely charged particles are. As a result, there is greater electrostatic attraction present in the smaller alkaline earth group atoms. This makes it more difficult to remove the valence electrons, which corresponds to higher ionization energies.
Therefore, the option (b) is correct - it have the highest ionization energies.
