Question

In alkaline earth metal which has highest ionization energy

Answer 1

Answer:

Beryllium

Chemical Symbol = Be

Explanation:

We must know about as to what ionization energy means!

So, ionization is energy is the amount of work done in bringing an electron out of its energy level (which is also popularly called the shell or orbit) from an isolated neutral and gaseous atom in order to convert it to a positively charged ion.

Having known about ionization energy, we must know it's trends in the periodic table.

So, across a period ionization energy increases while down a group the same decreases.

Now, for your, the first element of the group 2 i.e. alkaline earth metals is Beryllium. So, this element will have the maximum ionization energy.
