Dominic made the table below to organize his notes about mixtures. A 1-column table. The first column labeled properties of mixtures has entries that have no set composition, must have more than one state of matter, must have more than one substance. What mistake did Dominic make? The title should read “Properties of Solutions” because some mixtures do not have all of the properties listed. There is a definite recipe to make each mixture, so the composition of a mixture is set. Although it is possible to have more than one state, it is also possible to have only one state. A single substance can be used to make a mixture if the substance is composed of more than one element.

Although it is possible to have more than one state, it is also possible to have only one state.

Explanation:

The mistake Dominic made was stating that "although it is possible to have more than one state, it is also possible to have only one state."

Mixtures are impure substances with the following properties:

They have an indefinite composition

Their constituents retains their identities.

Constituents react differently to changed conditions.

They can easily be separated into constituents by physical methods.

There are two types of mixtures based on the number of phases coexisting:

Homogeneous mixtures have their constituents existing in just one phase.

Heterogeneous mixtures exists in at least two different phases.

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.
