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 size decreases across the rows of the periodic table
Atomic radius usually decreases from left to right across a period of the periodic table.
the number of protons
The order of the periodic table is made according to the atomic weights of the elements. The number of protons and neutrons in the nucleus make the atomic weight. Protons make the elements in order of the periodic table.
Atomic size decreases across a period
Atomic number increases by one as we move from left to right in a periodic table.
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
the atomic number.
The atomic number increases
electronegativity
The atomic number increases by 1 as one go across a row on periodic table. The elements are arranged in order of increasing atomic number.
