Question

what are the characteristics of period two elements on the periodic table

Answer 1

Answer:

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. Period 2 only has two metals (lithium and beryllium) of eight elements, less than for any subsequent period both by number and by proportion.

Answer 2

Answer:

All elements in row have the same number of electron shells.Each next element in a period has one more proton and is less metallic than its predecessor arranged this way ,groups of elements in the same column have similar chemical and physical properties reflecting the periodic law.
