Are period 1 elements more electronegative than period 2 elements?

No, period 1 elements are not more electronegative than period 2 elements. Electronegativity generally increases across a period from left to right, so elements in period 2 are generally more electronegative than elements in period 1.

What is the correlation of a period number with the elements of that period?

The period number of an element corresponds to the energy level of its outermost electrons. Elements in the same period have the same number of electron shells. As you move from left to right across a period, the number of protons and electrons increases, resulting in higher effective nuclear charge, which affects the properties of the elements.
