24
Q

Helium belongs to S block, but is still placed with P-block elements, why?

A

It has completely filled valence shell (1s2) and as a result, exhibits properties characteristic of other noble gases.

25
Q

Ionization enthalapy of alkali and alkaline earth metals

A

highly reactive, low ionization enthalapy

26
Q

why lithium and beryllium are not predominantly ionic

A

Lithium and beryllium are not predominantly ionic due to their atomic structure, low ionization energy, low electronegativity, and tendency to form covalent bonds.

27
Q

What are s-block and p-block elements known as

A

Representative or main block elements

28
Q

Halogens (17) and Chalcogens (16) follow properties of

A
  1. Highly negative electron gain enthalapies
  2. Readily add one or two electrons respectively to attain noble gas configuration
  3. Non-metallic character increases as we move from
    i. left to right of a period
    metallic character increases when we move from
    i. top to bottom of a group.
29
Q

Properties of D block elements

A
  1. Metals in nature
  2. Form coloured ions
  3. exhibit variable valence (oxidation states)
  4. Paramagnetic in nature
  5. Used as Catalysts
30
Q

Elements after Uranium are called

A

Transuranium elements

30
