The number of electrons in the atom increase from left to right and then from top to bottom.
Because in periodic table elements are arranged in increasing order of atomic no: and this indicate that in any given row no: of protons gradually increases one by one from left to right
They occupy all but the extreme top left, position (H) and the top right corner of the Periodic table.
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
The periodic table is arranged into Groups (i.e. columns) and Periods (rows). Now, each element is assigned an atomic number which is equal to the number of protons within its nucleus. Each element is then arranged in order of increasing atomic number from left to right. There is a more indepth answer relating to how the periodic table is arranged, however this is how they are "listed".
metals on the left, non metals on the right
Atomic number increases as you go from left to right
From left to right, metals , semimetals, non-metals and noble gases are arranged. This make the study of these elements easier.
The number of electrons in the atom increase from left to right and then from top to bottom.
There is a stair in the Periodic Table running along groups 13 to 17. The elements on the stairs are metalloids whereas the elements to its right are non-metals. Metals lie on the left side of the stairs.
Because in periodic table elements are arranged in increasing order of atomic no: and this indicate that in any given row no: of protons gradually increases one by one from left to right
look at any periodic table and you will see that elements are arranged from left to right and top to bottom in order of increasing atomic number.
They occupy all but the extreme top left, position (H) and the top right corner of the Periodic table.
Across a period, as we move from left to right, the electronegativity increases in the periodic table.

Non-metals are located on the very right of the Periodic Table. Metals are on the left.
When you move from left to right on the periodic table, the atomic number of the elements increase.
