it is atomic number
it decreases
Yes, as you move from left to right across the period.
The atomic weight (not mass) increase from left to right in a period.
First ionization energy increase
atomic radii increases from left to right in the periodic table from metal to non metal in the right
they increase left to right
Periods on the periodic table refer to the rows of elements. As the elements progress to the right, the atomic numbers increase, usually in steps of 1.
When you move from left to right on the periodic table, the atomic number of the elements increase.
Electronegativity increases as we move from left to right on the periodic table.
The atomic radius decrease from left to right in the periodic table.
it decreases
Increase
The properties which change regulary from top to bottom in a group and from leaft to right a period are called periodic property.
Yes, as you move from left to right across the period.
The atomic number and atomic masses increase as you move from left to right.
The atomic weight (not mass) increase from left to right in a period.
First ionization energy increase
