The 3-dimensional orientation of a sublevel is known as atomic orbital.
In quantum mechanics, Atomic orbitals are locations around an atom's nucleus where electrons are most likely to be at any particular time(specific orbits). These specific orbits exist in levels and can be broken down into sublevels.
Each sublevel has an orbital and it is oriented differently in 3-dimensional space.
The atomic orbital is a mathematical function that depicts how one or two electrons in an atom behave as seen in waves.

Nuclear fission is used enable to release energy in power plants. The constant collision of particles within the reactor, create most of the plants energy.
Answer:
0.156mol
Explanation:
Number of moles of a substance can be calculated from its mass by dividing its mass by molar mass i.e.
Number of moles (n) = mass/molar mass
Molar mass of PbCl4 is as follows, where Pb = 207.2g/mol, Cl = 35.5g/lol
PbCl4 = 207.2 + 35.5(4)
= 207.2 + 142
= 349.2g/mol
Using: mole = mass/molar mass
mole = 54.32 grams ÷ 349.2g/mol
mole = 0.1555
mole = 0.156mol
