Question

The elements beryllium, calcium, and strontium are all in group 2. What is the correct relationship of these elements regarding their ionization energy?

Answer 1

Answer:

⭐⭐⭐hey mate!⭐⭐⭐

_________________________________________________________

⚡⚡ In a group while going from top to bottom ionisation energy decreases.

⚡⚡In case of half filled and full filled orbitals IP is maximum.

⚡⚡Ionisation energy is defined as the amount to energy required to remove electron from an atom.

So the correct answer will be option (d)

Sr<Ca<Br

Hope it will help you...

Answer 2

Answer:D. Sr < Ca < Be  

Explanation:

Ionization energy decreases from top to bottom within a Group, because the valence electrons are further from the nucleus and therefore easier to remove.

Thus, Sr has the lowest ionization energy and Be the highest.

The correct order is Sr < Ca < Be.
