Question

How many valence electrons does aluminum (Al) have available for bonding? 1 2 3 4

Answer 1

3 valence electrons are available as the atomic no of Al is 13 so it's configuration becomes 2,8,3 therefore valence electrons = 3

Answer 2

Aluminum (Al) has three valence electrons for bonding.

Elements react in order to achieve noble gas electronic configuration by losing or gaining of electrons are called valence. These valence electrons are present in the outer shells. The chemical symbol of an “element aluminum” is Al.

The atomic number of aluminium is 13.

$Electronic\quad configuration\quad is\quad 1{ s }^{ 2 }2{ s }^{ 2 }{ 2p }^{ 6 }3{ s }^{ 2 }3{ p }^{ 1 }$

Therefore, three valence electrons does aluminium (Al) have available for bonding.
