Distillation of a mixture
They all look like there decaying and was left out or sat inside too long
Answer:
Orbitals
Shells
Energy Levels
Explanation:
Elements in the same period will have the same energy levels which is the same as orbitals and shells.
- The period of an element indicates the energy level in an atom.
- Elements in period 1 will have one energy level or shell or orbitals.
- Down a group this is not the case.
- The energy level increases from top to bottom.
- As we go down the group, we are transiting from one period to another.
Conditioning is the process of C. learning associations.
Two types of conditioning.
1) Classical conditioning
2) Operant conditioning.
Classical conditioning happens when an individual learns to associate two stimuli. This happens when an association is learned between an unconditioned stimulus and a conditioned stimulus.
Operant conditioning happens when an individual associates a behaviour with a consequence. For example, when a behaviour produces a good consequence; the individual is conditioned to repeat the behaviour to garner the same good consequence, and vice versa.
