Electronegativity increases across (left to right) the periodic table and decreases on going down.
From left to right and into the upper corner of the periodic table electronegativity increases. Fluorine is the most electronegative element, but the elements in group 18 generally have no electronegativity at all.
good ??????????????????????????????????????????????
No, columns of elements in the periodic table are called groups or families. Periods are the rows of elements that run horizontally across the table. Each period corresponds to the number of electron shells an element's atoms have.
The first ionization energy tends to increase across a period from left to right on the periodic table. This is due to the increasing nuclear charge and decreasing atomic radius, which leads to a stronger attraction between the electrons and the nucleus.
the numbers increase (going right) and decrease (going left)

The statement applies to the horizontal rows or periods in the Periodic Table is that properties change going across each row.

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.
The line going across
Electronegativity and first ionization energy both increase going up the Periodic Table.
The rows going across the periodic table are known as periods and contain elements with the same number of electron shells.

Going Up
The melting temperature properties generally change as you go from left to right in the periodic table by going down/decreasing.
