2. oxygen ⇒ molecules (oxygen exists in molecular form as O2)
3 Magnesium ⇒ matalic lattice ( Magnesium is a metal FCC crystal Structure :) )
4 Aluminum⇒ covalent network (since it is situated in the middle of the group and posses amphoteric properties too)
The radiation one typically encounters is one of four types: alpha radiation<span>, </span>beta radiation<span>, </span>gamma radiation<span>, and x radiation. </span>Neutron radiation<span> is also encountered in nuclear power plants and high-altitude flight and emitted from some industrial radioactive sources.
