Two things happen when you move from right to left. First, the number of valence electrons increases from one to eight. Secondly, the number of protons increases from three to ten. There is also the transition from alkali metal to alkaline earth metal to metalloid to nonmetal to halogen to noble gas.
The electronegativity increases across the periods from left to right.
As you move left to right across the second period of the Periodic Table ionization energy increases. The trend for ionization energy is increasing up groups and across periods.
the size of cations decreases as we go left to right in the periodic table
ionization energy increases

Across a period, as we move from left to right, the electronegativity increases in the periodic table.
moving from left to right across a period, one electron is added for each element.example: Boron has 3, Carbon has 4.
When moving left to right across the PT the ionization energy increases. As you go down, the ionization energy, decreases.

Across a period, as we move from left to right, the electronegativity increases in the periodic table.
Electronegativity increases as you move across the periodic table from left to right.
Electronegativity increases as you move across the periodic table from left to right.
Atomic radii decreases on moving from left to right as the effective nuclear charge increases.
Electronegativity increases across (left to right) the periodic table and decreases on going down.
Atomic radius usually decreases from left to right across a period of the periodic table.
Electronegativity increases across a period (left to right).
