Answer:
They may react in the air and become an acidic gases.
Gallum: Z = 31
electron configuration: [Ar] 4s^2 3d10 4s2 4p1
Highest energy electron: 4p1
Quantum numbers:
n = 4, because it is the shell number
l = 1, it corresponds to type p orbital
ml = may be -1, or 0, or +1, depending on space orientation, they correspond to px, py, pz
ms = may be -1/2 or +1/2, this is the spin number.
Answer:
A mixture is classified as a solution when there is an homogeneous mixture of the two or more substances involved in a given medium.
A mixture is classified as a suspension when there is a heterogeneous mixture of undissolved particles in a given medium.
A mixture is classified as a colloid (false solution) when the individual solute Particles are larger than the particles of true solution, but they are not large enough to be seen by the naked eye. The solutes can scatter light rays.
