In general where would you find elements x y and z on the periodic table

What exactly do you mean by elements 'x', 'y', and 'z'? You can search for an atom on the periodic table by searching for its atomic number, or you can base your search on atomic radius, electronegativity, or ionization energy.

Atomic radius increases as you move down the groups in the periodic table. Electronegativity and ionization energy decrease as you move down the groups, but increase as you move from left to right on the periodic table.

I hope this answered your question! Not entirely sure what you mean by elements x, y, and z.

It dont even matter because at the end of thre day we gone life like it ius s

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

explanation

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.
