Question

In second period of the modern periodic table which element has the more atomic radius and why

Answer 1

Explanation:

For all elements in period 2, as the atomic number increases, the atomic radius of the elements decreases, the electronegativity increases, and the ionization energy increases.

Answer 2

Answer:

in second period of modern periodic table following element are present Li, Be, B, C ,N,O ,F,Ne and from left to right in periodic table atomic radius decrease due to increase of electron but shell no. constant so Li has highest atomic radius in 2nd period element
