How is a mixture of water and sugar separated

The easiest way to separate a mixture

of sugar and water is to use distillation,

a process that separates substances

based on their different boiling points.

Sugar does not boil, but the point

at which it crystallizes (320 degrees

Fahrenheit) is much higher than the

boiling point of water (212 degrees

Fahrenheit), so when you boil a mixture

of sugar and water, the water turns to

steam and leaves the sugar behind.

You can collect the steam to capture

the water, effectively separating the

sugar and water. If you are keen to learn

more about distillation, evaporation and

crystallization, this process, involves all

three.

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
