In period 2, element X is to the right of element Y. Then, find which of the elements have:
i) Low nuclear charge (ii) Low atomic size (iii) High ionization energy
(iv)High electro negativity (v) More metallic character

In period 2 element X is to the right of element Y . Then , find which of the element have : Low nuclear charge

In period 2 element X is to the right of element Y . Then , find which of the element have : Low atomic size

In period 2 element X is to the right of element Y . Then , find which of the element have : More metallic character

In period 2 element X is to the right of element Y . Then , find which of the element have : High ionization energy

In period 2 element X is to the right of element Y . Then , find which of the element have : High electronegativity

Which one is true ? i) More nuclear charge, more ionization energy. ii) More screening effect, less ionization energy. iii) More atomic radius, more ionization energy.

Identify the elements that has the lower ionization energy in each pair of the following and mark it with a symol . (i) Mg or Na (ii) Li or O (iii) Br or F (iv ) K or Br

PASSAGE - 3 : In modern periodic table there is gradation in the properties of elements. In a period the Ionisation energy, Electron affinity, Electro negativity, Non-Metallic nature increases. In a group the atomic size, metallic nature, reducing properties and densities of elements increases. The pair of elements with equal electro negativities
